Ghostscript change history (detailed)

>     Merge change from trunk.

>     Remove ARCH_STRUCT_ALIGN_MOD entirely and revert to
>     ARCH_ALIGN_MEMORY_MOD not having the extra jmp_buf
>     alignment requirements. This satisfies the assumption
>     that structure alignment and sizeof(ref) agree in
>     the Ghostscript code and should finally fix 687643.

>     Also add a cast back to jmp_buf in the alignment
>     macro setjmp_.h. Fixes bug 688698. Patch from
>     Alex Cherepanov.

>     Port the fix for bug #688149 from trunk. Originally committed by Ray
>     Johnson.

>     Fix so that dictionaries that grow preserve attributes.
>     Several problems reported including a potential security
>     hole when in SAFER mode. Thanks to mat Gh Savulescu
>     (SaGS) for the bug report, the patch and excellent
>     analysis of the problem.

>     DETAILS:
>     Ordinarily dictionaries have unprotected, non-exectue
>     status, but it is possible to "grow" executable or even
>     "read-only" dictionaries (contact Ray Johnston for an
>     explanation as provided by mat Gh Savulescu). The bug
>     in idict.c would not preserve the attributes, making
>     the dictionary not executable, and not readonly even
>     if those were the original attributes.

>     EXPECTED DIFFERENCES:
>     None. (we don't run regression in SAFER mode and don't
>     rely on 'special' dict attributes).

>     Port fix for 688686 segfault in find_bit_map() to 8.54 branch.

>     DETAILS:

>     The addition of the compressed encoded color logic created a problem for
>     the psdrgb device.  This device shares most of its code with the psdcmyk
>     device.  The common print_page procedure uses devn_unpack_row.  This
>     routine was modified to work with the compressed encoded color values.
>     However the psdrgb device does not use the compressed encoded color logic.

>     The fix consists of checking for the presence or absence of a compressed
>     color list pointer.  The presence of this pointer indicates if the compressed
>     color logic is being used.  The appropriate uncompress logic is used.

>     pdfwrite : Implementing ColorImageAutoFilterStrategy, GrayImageAutoFilterStrategy.

>     DETAILS :

>     This patch implements ColorImageAutoFilterStrategy, GrayImageAutoFilterStrategy
>     destiller parameters, and applies them for choosing image encoding filters
>     when Ghostscript is built with Luratech filters.

>     1. Since the old architecture defines common image parameter lists for
>     pswrite and pdfwrite, now we need to pass CompatibilityLevel to
>     those common modules. Doing that in a hackish way with defining
>     a new field gx_device_psdf::ParamCompatibilityLevel,
>     and setting it whenever that stuff is called from pdfwrite.

>     2. Using it for the filter choice in psdf_setup_image_filters.

>     3. Enhance psdf_get_image_params and psdf_put_image_params with
>     ColorImageAutoFilterStrategy, GrayImageAutoFilterStrategy (gdevpsdp.c).

>     4. Passing the lossless option for JPXEncode filter in setup_image_compression,
>     and using that filter for lossless compression instead FlateEncode/LZWEncode
>     when it is available, depending on ColorImageAutoFilterStrategy, GrayImageAutoFilterStrategy.

>     5. With CompatibilityLevel>=1.5, with 1bpp images we choose JBIG2Encode instead
>     FlateEncode/LZWEncode when it is available.

>     Thus, when Luratech filters are available, with CompatibilityLevel>=1.5,
>     Luratech filters work by default.

>     EXPECTED DIFFERENCES :

>     None.

>     Currently the new code is disabled with the macro NO_INVISIBLE_LEVELS
>     defined in gxalloc.h .

>     The performance flaw happened in revision 5980.
>     Before it the memery manager created "invisible" save levels
>     when the changes list becomes too long and needs a big time for
>     restoring l_new marks. The idea was to skip marls for
>     older changes so that they don't consume processor time.
>     The cost was an extra growth of the changes list,
>     because such changes are stored at second time
>     if happen again after the "invisible" 'save'.
>     While fixing the bug 68815 this optimization was lost
>     because it was not documented.

>     In same time, "invisible" 'save' levels appear logically incorrect,
>     because they cause the problem documented in the bug 68815.
>     This change implements same idea (the skipping of old changes
>     while 'restore'), but it does that with no extra 'save' levels.

>     The new implementation maintains a pointer
>     gs_ref_memory_t::scan_limit, which points
>     to a middle element of the changes list.
>     Elements after that pointers do not restore
>     l_new mark during 'restore'. Besides that,
>     this change introduces a new kind of change list elements,
>     which is marked with AC_OFFSET_ALLOCATED in the 'offset' field.
>     Such elements do not represent a memory content change,
>     but they represent an allocation event for 'ref' arrays.
>     The l_new mark is restored for those refs,
>     which were allocated after the change element
>     pointed by gs_ref_memory_t::scan_limit.

>     To simplify debugging, we define a new switch
>     NO_INVISIBLE_LEVELS in gxalloc.h .
>     When NO_INVISIBLE_LEVELS is zero,
>     an algorithmically equivalent change happens in isave.c
>     and igcref.c, and other modules are not affected.
>     In this case :

>     1. Factored out a new function mark_allocated (isave.c).
>     2. Added a new argument to save_set_new, save_set_new_changes
>        to know that it is called for an invisible level (isave.c).
>     3. Factored out a new function igc_reloc_ref_ptr_nocheck (igcref.c).

>     When NO_INVISIBLE_LEVELS is 1 :

>     1. Invisible save levels are not created
>        (the change to alloc_save_state in isave.c).
>     2. Instead that, it creates a new kind of alloc_change_t element,
>        which is marked with AC_OFFSET_ALLOCATED in the 'offset' field.
>        Such element points to the beginning of a newly allocated 'ref' array
>        (either packed or not) (see alloc_save_change_alloc in isave.c).
>     3. The new function alloc_save_remove removes such elements when
>        the object is being removed explicitely.
>     4. save_set_new is expanded to process the new kind of alloc_change_t elements.
>        With such elements it calls mark_allocated (see above),
>        so that the effect is same as before the patch.
>     5. The scanning of allocated objects in save_set_new is removed
>        due to (3).
>     6. save_set_new_changes is extended with computing the size of
>        newly allocated 'ref' arrays, which are processed during the scan.
>        It appears to be close to what save_set_new did while scanning
>        allocated objects (the variable 'changed').
>     7. The new field gs_ref_memory_t::scan_limit stores a termination
>        condition for scanning objects in save_set_new_changes.
>        The value is stored when save_set_new_changes is called
>        from alloc_save_state as it was for creatng an invisible save level.
>        Rather the new code doesn't create an invisible level,
>        the scan termination condition work as it were created.
>     8. save_set_new_changes uses the variable 'changed'
>        for a proper setting of the termination condition.
>        The condition is not exactly equivalent to the
>        old one, because the old code also accounts
>        a scanning of non-ref objects, but the new code
>        doesn't bother with them. Therefore new termination conditions
>        appear in some different points than invisible levels did.
>        Therefore the behavior isn't algorithmically equivalent.
>     9. The new code always restore to a 'visible' level.
>        In same time, doing a 'restore', some of l_new marks
>        may be left unrestored due to the scan tremination condition.

>        number of recently changed objects by marking with l_new.
>        Older changes loose the l_new mark and their further changes
>        will be stored again in the 'changes' list.
>        This causes an extra growth of the 'changes' list,

>     10. The garbager implements a special processing for
>        AC_OFFSET_ALLOCATED elements. The 'where' pointer is not
>        enumerated and isn't tracked while the marking phase.
>        Instead that the garbager calls a special function

>        igc_reloc_ref_ptr_nocheck is used to relocate
>        'where' pointers. See comments in code.

>     Fix (pdfwrite) : The font copying and the font comparizon didn't work with segmented True Type data.

>     Bug 688611 "Font included in the PDF file several times".

>     In Postscript documents Trus Type font data are segmented
>     to fit into a maximal Postscript string.
>     If a True Type table is bigger, it must be segmented.
>     When creating a stable font copy such case is rare,

>     In the supplied test case True Type font is so wrongly segmented,
>     that 'cvt' table consistes of 2 segments, rather it could fit into a single string.
>     Due to that the old code accessed occasional data after a segment break.

>     non-zero exit code, then the 'test' operand is not needed. For example,
>     if rev. 6170 corresponds to 8.53, and the current HEAD is 6647, then the

>     search-svn-revs 6170 6647 'bin/gs -dBATCH -dNODISPLAY -dNOPAUSE -q coloraerial.pdf'

>     The gs output is captured in 'test.log' so that output can be examined (for

>     Currently all spot colors, in either a DeviceN or a Separation color space,

>     DETAILS :

>     Bug 688537 "A very slow rendering to spotcmyk".

>     The first attempt caused a regression with pkmraw and
>     has been undone. This patch accounts pkmraw effects,
>     which are explained below as "Auxiliary changes".

>     This patch creates a special branch in gx_default_fill_path
>     for filling a path with a colored halftone.
>     It installs a clipper device and then renders
>     a rectangle through it, using the halftone color painting method immediately.

>     Auxiliary changes :
>     The new branch in gx_default_fill_path calls gx_cpath_intersect
>     for intersecting the filling path with the clipping path.
>     The latter calls gx_default_fill_path again for
>     converting a path into a rectangular clip list.
>     Now we pass the fill adjastment parameters
>     of the main gx_default_fill_path invocation
>     to the inner invocation.
>     Doing so because we need the intersection to be closer to
>     what the regular algorithm fills. The new function
>     gx_cpath_intersect_with_params works for that.
>     Particularly it causes dropout prevention to work
>     for clipping, when a character is filled with a halftone.

>     The clip list accumulator device now sets
>     gx_device::memory to a real memory manager.
>     Before now it was NULL. The new code
>     uses it to allocate working data for the dropout prevention code.

>     Besides that, gx_cpath_intersect_with_params
>     now applies fill adjustment in the special
>     branch for a rectangular path intersection.

>     The flag OLD_CODE_COMPATIBILITY minimizes raster differences
>     for easier testing. It should be removed later,
>     because we believe that the old code is not perfect :
>     it doesn't pass fill adjustment through gx_cpath_intersect
>     while filling with a shading color.

>     1. Moving char_name from the charproc structure to pdf_char_proc_ownership_t,

>     2. pdf_is_charproc_compatible is changed to a weaker condition
>     to allow to merge char procs with different names.
>     However we prefer fonts with a compatible encoding, which are attached to same PS font,
>     in order to prevent mixing glyphs from various fonts.

>     3. charproc_compatibility_data_t is defined to reduce the gx_device_pdf::find_resource_param bogus.

>     4. pdf_char_widths_from_charprocs is a new function for reconstructing
>     real_width when a PDF Type 3 font is attached to another PS font.
>     Due to historical reason, real_width is a property of the attachment,
>     rather in novadays it should be a property of PDF font.
>     It happens because a PDF font may migrate to another PS font due to charproc merging,
>     especially in case of glyph variations.

>     5. The condition for involving pdf_find_same_charproc has been changed
>     in pdf_end_charproc_accum to a weaker one, to allow to merge with charprocs from other fonts.
>     With the old condition a charproc didn't merge when appears in a font at the first time,
>     so it never merged with ones from other fonts.

>     6. Added a marking of glyph names in pdf_char_proc_ownership_t for the garbager.

>     7. Now we mark glyph names for garbager for all simple fonts,
>     except synthesised bitmap fonts (which use char codes instead glyph names).
>     The old code did for non-bitmap Type 3 only, and theretore it can have an indeterminizm

>     It happens because the space glyph appears same for two fonts, which form a single text,

>     pdfwrite : Implementing composite fonts with Type 3 descendents.

>     DETAILS :

>     Bug 687875 "pdfwrite : Type 0 FMapType 9 font with a Type 3 descendent converts to bitmaps".
>     Bug 687298  "(pdfwrite) composite font with Type 3 descendent".

>     The old code converted such fonts into bitmap fonst.
>     The new code converts them into multiple Type 3 fonts ;

>     A. If a composite font uses a CMap mapping,
>     the Type 3 font descendent may use any CID from the CMap.
>     Therefore such single Type 3 font is being converted into
>     multiple Type 3 fonts, each of which is restricted
>     with 256 characters by the PDF specification.

>     B. If a composite font has multiple Type 3 descendents,
>     each descendent form a separate Type 3 font in the PDF output
>     (or multiple fonts if it falls into both cases (A) and (B)).

>     This is a case-driven implementation, which is done with adding special branches into
>     scan_cmap_text and process_text_modify_width for handling the failed cases.
>     Other new cases (which we have no samples for) may may need further improvements.

>     Move back-up CharString construction procedures (RD, ND, ...) to a special

>     Bug 688464

>     DETAILS:

>     Some broken fonts forget to define CharString construction procedures because
>     non-PostScript font rasterizers don't detect this error. Ghostscript has
>     a back-up definitions of the procedures that do their job and issue a warning.

>     Other correct but old-fashioned fonts define CharString construction procedures
>     in userdict. We had the back-up procedures defined above userdict, where they
>     preempted the userdict definitions and issued a bogus warning. This patch moves
>     the definitions below userdict.

>     Partial fix for 688413 DeviceN under implements 'attributes'

>     DETAILS:

>     This patch implements the passing of DeviceN attribute color spaces into the graphics library.  The patch consists of the following pieces:

>     1. In lib/gs_devn.ps:  Attribute color spaces are processed like another color space and then .attachattributecolorspace is called to associate the attribute color space with a DeviceN color space.

>     2. In lib/pdf_draw.ps: Logic wa added to resolve references to attribute color spaces in PDF DeviceN color spaces.

>     3. In src/zcsdevn.c and src/gscdevn.c: The implementation of the .attachattributecolorspace is done.

>     4. Header files were modified to add the attribute color space structures and fields.

>     5. GC enumeration and relocation logic was added.

>     DETAILS:

>     The cache detection was both slow and unreliable, especially given the
>     spread of cpu and memory speeds now available. Furthermore, no use was
>     being made of these attempted cache size measurements. We have therefore
>     removed them as a simplification.

>     Choosing the blocksize of large inner loops can indeed be a good
>     technique, but this is a case of premature optimization. Moreover,
>     it's usually better to test at run time with the actual algorithm
>     in question than try to work from a general number.

>     Enable use of "Bold" in BaseFont name when doing font substitution from PDF
>     files that don't embed all fonts. Bug 688432 for customer 670.

>     DETAILS:

>     There is not really a 'Bold' flag in the FontDescriptor Flags (the ForceBold
>     infers a Bold font, but is not present for all Bold fonts since it has a
>     different meaning).

>     The pdf_font.ps logic had logic for "Narrow" in the font name, but not "Bold".
>     Enabling recognition of "Bold" works for this file and probably most others.

>     EXPECTED DIFFERENCES.

>     unknown, but if so progressions will be updated.

>     pdf_find_same_resource now works for named resources.

>     Changes to gdevpdfo.c :

>     Since pdf_substitute_resource in pdfmark_EP can associate one object
>     with multiple names, the freeing logic is improved
>     to avoid crashes due to dual freeing of objects.

>     General consequences :

>     1. The new code writes an object whenever it is defined,
>     with no regard whether it is referred or not.
>     If one needs an optimization with skipping
>     unreferenced objects, the named object handling logics
>     to be changed dramaticly with distinguishing a storage for
>     all objects and a storage for currently named objects.
>     An object must get special mark whenever it is referred
>     (it would be a big distrubuted change through the code).
>     Writing all objects to be delayed until the document end,
>     and a garbage collection to be implemented for that storage.

>     2. We do not reproduce a part of Adobe Distiller behavior,
>     which allows to modify objects when they are being created between
>     pdfmark_BP and pdfmark_EP. Particularly this prohibits self-referenced objects.
>     This is a strong consequence of (1).
>     (Note that the bug 687560 examples miss a big class of cases when
>     the creating object is referenced with /PUT pdfmark during its creation.
>     Those examples show only cases when it is being modified.).

>     3. Users should not define "pdfmark libraries" with multiple object definitions,

>     for a better modularity of document creation algorithms.
>     However we do not have enough engineering resources to

>     Now we provide explicit Resources sinse that reader version is widely distributed.

>     The Resources dictionary of a Type 3 font is a PDF 1.2 feature.
>     To provide a compatibility to PDF 1.1,
>     the old code implemented a special mechanizm for transmitting resources of
>     a Type 3 font to pages, which use the font.

>     This patch disables that mechanizm when CompatibilityLevel >= 1.2 in gdevpdte.c .
>     Instead that it creates Resources of a Type 3 font as a cos_dict_t instance
>     in gdevpdtf.h, gdevpdtt.c, and writes it out when the font is being written
>     in gdevpdtw.c .

>     repeatedly creating a ReusableStreamDecode filter for the DataSource
>     element. Fixes bug #687117 for customer #850.`

>     DETAILS:

>     The 'limit' value used to trigger a GC process was sometimes set to a

>     on every interpreter loop past the gc_signal check.

>     Even with this fixed, the file ran slower than the -dNOGC case because
>     the PDF interpreter 'csset' logic would set the ICCBased colorspace that
>     would create a new ReusableStreamDecode filter from the DataSource on
>     every 'Do' of the many images used to paint the logo (line by line).
>     The reusablestreamdecode logic would allocate a 64000 byte string (only
>     3144 bytes of which were actually retained) so after about 8 images the
>     allocations would exceed the limit and another GC would run (freeing up
>     the space used by those 8 large strings and 7 of the small ones along
>     with miscellaneous stuff).

>     The fix for the second issue was to check if the ICCBased colorspace
>     had already been 'resolved' (was a dicttype instead of a procedure that

>     This patch consists of 2 parts :

>     1. A hack for synchronizing the clipping path in 'pdfmark'.
>     We need to use a hack, because the implementation of 'pdfmark'
>     is based on the device method put_params, and
>     there is no regular way to pass the imager state or the clipping path through it.
>     The hack paints something outside the device bbox,
>     so that the painting doesn't appear in the output.

>     2. An improvement to the pdfwrite device,
>     which skips a stroking, if it appears entirely outside the clipping box.
>     That improvement appears some imperfect due to a compatibility
>     to the hack (1) - see comment in code. The imperfection is
>     the synchronization of a clipping path when a document strokes outside
>     the clipping box. We believe that such cases are rare,
>     so the imperfection isn't important.

>     The filling algorithm : optimize paths with many subpaths.

>     DETAILS :

>     Bug 686996 "Orientation has massive effect on render time".
>     It fills a path consisting of 4440 subpaths,
>     each of which is a quasi-rectangle
>     (or a rectangle with a fixed_fraction noise).

>     If a path has over 50 subpaths,
>     we try to merge subpaths by common vertical lines.
>     This works around a poor 3d party software,
>     which generates a path as a huge number of contacting rectangles.

>     An additional complexity happens due to the sample document defines multiple
>     quasi-colinear lines instead colinear ones. An example : {{362254, 42905},
>     {362253, 204152}} and {{362253, 42881},{362253, 204152}}.
>     We believe that with a huge number of contours the precision of the rendering
>     doesn't need to be so strong as with a small number.
>     Therefore we replace quasi-colinear lines with colinear ones.

>     Another smart point is which pairs of lines to be checked for colinearity.
>     Obviousely checking all pairs would be too slow. Probably we can assume that the

>     Ghostscript Bug 688126 "Wrong line join".

>     1. The old code applied a bewel join while flattening a curve.
>        Such behavior appears incompatible to Adobe CPSI 3010.105.
>        Language.htm said that it was done with .setcurvejoin
>        for a compatibility to Adobe implementations.
>        We believe that modern Adobe implementations are not such,
>        and therefore we change the default value of .setcurvejoin to -1,
>        which actually disables a curve join by default.
>        The documentation is being updated accordingly.

>     2. Since round join always paints a full circle (see comment in add_round_cap),
>        and since such circle doesn't appear when CPSI paints a flattened curve,
>        we conclude that round join isn't applied to flattened curves.
>        Therefore we change the condition in gxstroke.c
>        to replace round join with bevel join for flattened curves.

>        Note that PDF 1.5 requires to paint a "pieslice-shaped figure",
>        rather than PDF 1.4 and PLRM3 does a round.

>     The old code scanned Encoding and put a Metrics dictionary element
>     for each element of Encoding. However Encoding could contain dummy

>     Fix for 687989 PDF to any format raises /invalidfont in /R21.  The test
>     file was created by an imposition program.

>     DETAILS:

>     The given file (the one with the four pages imposed together) has:

>     1.  A Page dict with form Xobjects and the /R21 font is not in the
>         Resources/Font dict.
>     2.  The Pg3 form XObject has the /R21 font in the Resources/Font dict.
>     3.  /R19 is a Type3 font.  There is not a Resources entry in the dict.  This
>         font uses both the /R13 ExtGState and the /R21 font.

>     To find the /R13 and the /R21 resources, Ghostscript is first looking in
>     the /R19 font.  Since it is not present (no Resources in /R19), Ghostscript
>     then searches the Page dict.  Once again the resources are not found and then
>     the InvalidFont error is generated.  (Ghostcript is silent about the missing
>     ExtGState /R13.)

>     From page 391 of the PDF REference, version 1.6 on the entries in the dict for
>     a Type3 font:

>     "Resources  dictionary (Optional but strongly recommended; PDF 1.2) A list of
>     the named resources, such as fonts and images, required by the glyph
>     descriptions in this font (see Section 3.7.2, "Resource Dictionaries"). If any
>     glyph descriptions refer to named resources but this dictionary is absent, the
>     names are looked up in the resource dictionary of the page on which the font
>     is used. (See implementation note 64 in Appendix H.)"

>     This implies that Ghostscript is following the correct path for finding the
>     resources /R13 and /R21.  (However one can make a case for a 'liberal'
>     interpretation of the spec. that implies that the form XObject resources
>     should also be checked.)

>     This fix checks the current resources when the Resources dictionary is not
>     present in a type 3 font.

>     I do not know why Acrobat 6.0 Pro does not find /R13 but does find /R21.  If

>     Partial fix for 687814 dithering artifacts.  The given test file shows
>     some faint halftone dots in the background when rasterized using the
>     bmp256 device.

>     DETAILS:

>     The problem is caused by a combination of factors that aggravate the
>     situation plus some things in the color look up logic that cause minor
>     errors in the calculations.

>     The aggravating factors:

>     By default, Ghostscript uses a 16x16 halftone cell for low resolutions,
>     i.e. below 150 dpi.  (I do not know the reasons why and it seems like a
>     poor choice to me.  However for now, I am not changing the halftone.)
>     The bmp256 device utilizes a 6x6x6 RGB color cube.  Thus there are 1281
>     levels ((16 x 16 x 5) + 1) for each halftoned colorant.  This gives a step
>     size between each level of 0.00078.  Thus even very small errors in the
>     calculations become visible as faint halftone dots.

>     The given test file is using a CalRGB color space.  The WhitePoint is
>     [ 0.9505 1 1.089 ] which is the standard D65 white point.  However with
>     the given CalRGB parameters and a pure white RGB input (1 1 1). the
>     resulting XYZ is [0.9505 0.99999 1.089] which has a very small error in
>     the Y value.  (However the error is small enough that one would not expect
>     it to be visible.)

>     The calculations in Ghostscript's halftoning logic for determining the
>     halftone level truncate values.  With an RGB process color model, this
>     means that only a pure white is not halftoned.  Thus the small error
>     mentioned in the previous paragraph becomes visible.  Note:  The truncation
>     effects work the other way in a CMYK process color model, which is why
>     we do not see this problem with shades that are nearly white in CMYK
>     halftoned output.

>     The calculation errors:

>     To save CPU time, the color look up logic did not interpolate table
>     entries which were closer that 0.01.  Thus output values could have an
>     error as large as 0.01.

>     The color look up logic clipped table entries to the specified output
>     range.  This can cause errors with interpolated values when the interpolation
>     involves one table entry that is clipped and one entry that is not clipped.

>     The changes in this fix:

>     The calculations that determine the halftone levels was modified.  Actually
>     it was simplified.  Prior to the DeviceN changes (in revision 8.00) there
>     were three separate calculations for halftone levels.  There was a separate
>     calculation for Gray, RGB, and CMYK color spaces.  Revision 8.00 changed
>     the halftoning to be based upon the device's process color model (instead
>     of the color space) and merged the RGB and CMYK calculations.  The two
>     separate calculations were kept to minimize regressions during the DeviceN
>     effort.  This change basically keeps the logic that had been used for Gray
>     process color models.  This version of the calculation does not have the
>     truncation problems that were present in the RGB/CMYK calculation.  Another
>     simplification was removal of some logic that was checking for additive
>     versus subtractive process color model.  Once again this logic was present
>     only to minimize regressions compared to pre 8.00 results.  The final
>     result is that this calculation is much simpler, faster, and gives a better
>     result.

>     The 'do not interpolate' criteria was reduced to 0.001.  Once again this
>     can add to the CPU time.

>     Changes which are not in this fix:

>     The clamping of look up table entries was not changed.  Changing this
>     requires that the we would have to clamp the output after the table lookup.
>     The errors are small but they are large enough that problems are still
>     seen with the bmp256 device and a 16x16 halftone cell.  There are several
>     different paths through this logic and thus the probability of creating
>     worse errors is relatively high.  This change would add slightly to the
>     CPU time but is required to get the correct result.

>     EXPECTED DIFFERENCES:

>     This change produces small changes in the halftone levels.  The changes in
>     the 'do not interpolate' value affects many files which use CIE or ICC
>     color spaces.  Between these two changes, this fix affects 165 files.

>     This happened with unlinear color devices only,

>     1. Passed the quadrangle size information to quadrangle_color_change.

>     2. Used it with unlinear color devices.

>     3. Trying to use it with a linear color device doesn`t

>     Conveys input tray selection info (/ManualFeed and /MediaPosition)
>     setpagedevice requests to PCL devices. Fixes bug #687899.

>     DETAILS

>     1. The behavior of MediaPosition is changed significantly. Previously,
>        it was ignored (i.e. omitted altogether from setpd merging). Just
>        adding it to setpd merging would not be good - if set at the PS
>        level, then it would get checked for equality at the C level (by
>        zmatchmedia), and fail horribly if it didn't match. In accordance
>        with the PLRM3 text (it will be honored provided it can satisfy the
>        normal media matching), in the new version a mismatch simply adds a
>        .001 penalty to the matching score.

>     2. The ljet4 device now contains ManualFeed and MediaPosition fields,
>        with appropriate putparams logic to set them.

>     3. The MediaPosition and ManualFeed strings now create an ESC & l H
>        init string, according to the following logic. ManualFeed sends
>        ESC & l 2 H; if ManualFeed is false (or not set), then MediaPosition
>        0 sends ESC & l 5 H, and MediaPosition1 sends ESC & l 1 H. If none
>        of these are set, then no extra init string is generated.

>        Obviously, for this feature to be useful, there needs to be an
>     InputAttributes dictionary in effect, for which the PageSize of
>     positions 0 and 1 match the PageSize of the setpagedevice request.
>     [Actually, if only ManualFeed is desired, then there is no need to
>     fiddle with InputAttributes].

>     pdfwrite : Implementing a viewer's resource memory control, part 1.

>     DETAILS :

>     This patch implements a primitive viewer's resource memory control.

>     A new device parameter MaxViewerMemorySize specifies the number of bytes
>     available for storing resources in the viewer's memory.
>     This parameter defined almost for future extensions.

>     Currently we distinguish two cases only : if the parameter is greater
>     than 10000000 bytes, no resource control is being applied,
>     i.e. pdfwrite assumes that the viewer can store all resources of entire document.
>     Othervise pdfwrite assumes that the viewer can store resources of a single page.

>     In the second case pdfwrite cleans internal resource caches after each page,
>     so that any new resource usage will generate another resource instance
>     in the output PDF file.

>     To inform the viewer that the resources may be cleaned,
>     we add a new key to a page contents stream dictionary.
>     This is our extension to the PDF specification in order to control
>     the resource management in the viewer.
>     The new key name is /.CleanResources.
>     Currently we provide only the value /All. It means that resources
>     may be cleaned *after* ending the contents stream.

>     In future on necessity we can split a page contents stream into substreams
>     and provide a finer control by resource types with providing
>     more values for the key /.CleanResources.

>     When the viewer is informed with allowing to clean resources,
>     it is not obliged to do so. Further resource appearences simply replace
>     old ones, if they have same resource name.
>     Actually now this happens only with font and CID font resources.
>     Other resource instances may persist in the viewer's memory until
>     the viewer's garbager frees them when they are not
>     referred from resource tree dictionaries.

>     The resource control is mainly intended for ps2write.
>     An implementation of the viewer's side (in opdfread.ps) will be a separate patch.

>     Note that when a resource control is being applied,
>     the output document size may increase significantly.

>     Currently we don't add MaxViewerMemorySize to user's documentation,
>     because it depends on another undocumenmted parameter ForOPDFRead
>     through the ResourcesBeforeUsage flag. First we need to take a decision
>     whether ps2write will become a new Ghostscript device or it stays a tool
>     represented with a script. The latter gives more flexibility to users
>     about composing the header procsets of the generated Postscript document.

>     Fix for 687696 PDF 1.4 transparency can use large chunks of memory.
>     Prior to this fix the handling of PDF 1.4 transparency features used one
>     or more full size image buffers.  With high resolutions and large images,
>     these buffers can be multiple gigabytes.  As a result, we were not able
>     to handle these files.

>     DETAILS:

>     PDF 1.4 transparency is handled by a device which is inserted into the
>     device chain.  Prior to this fix, this device was via the 'device filter'
>     logic.  With this fix, the PDF 1.4 transparency device is inserted via
>     the compositor device mechanism.  This change was made since the device
>     filter logic did not allow other devices to control where the PDF 1.4
>     transparency device is placed in the device chain.  There is a device
>     proc which implements the create compositor action.  This allows more
>     control than the device filter logic.

>     The first step in this fix was to convert the PDF 1.4 transparency
>     logic to use the create compositor mechanism.  For situations in which
>     the clist logic is not being used, the PDF 1.4 transparency device is
>     created and placed in the same location in the device chain as it was put
>     by the device filter logic.  In this situation, there is very little
>     logical difference in the operation of the PDF 1.4 transparency.

>     For situations in which the clist is used, there are two PDF 1.4
>     compositing devices created.  There is one device before the clist when the
>     clist is being written.  There is a second device after the clist when
>     the clist data is being read.

>     The device before the clist serves two purposes, it provides a means for
>     implementing the process color model for the PDF 1.4 compositing.  (The
>     PDF 1.4 compositing may used a different process color model from the output
>     device.)  Thus this device has color_info and encode/decode color procs
>     which match the PDF 1.4 blending color space.  This device also ensures
>     that the PDF 1.4 blending parameters (blend mode, shape, opacity, etc.)
>     are passed through the clist to the second PDF 1.4 device.

>     The second PDF 1.4 device (the one when the clist is being read) is the
>     same PDF 1.4 compositing device which is used when the clist is not being
>     used.  This is the device which does the blending operations.  Since the
>     device is after the clist, the buffers that it needs are the size of a
>     single band instead of the full page.  This device is placed prior to
>     the memory device which is used for drawing the raster data.

>     Two changes were made in the 'create compositor' logic.  The imager state
>     was being passed as a 'const'.  It is no longer const since the PDF 1.4
>     transparency compositing changes the cmap procs in the imager state to not
>     use transfer functions during color calculations.  The transfer functions
>     are applied later (and the cmap procs restored) when blended image data
>     is output from the PDF 1.4 compositing buffers.

>     The second change to the create compositor logic is the addition of two
>     more procedures to the gs_composite_type_t.procs list.  These procedures
>     are used by the clist device create compositor routines.  The first
>     is used to create the PDF 1.4 clist write device.  The second saves and
>     restores the color_info field for the clist device (see below).

>     Default versions of the added gs_composite_t.procs were also added for
>     use by the other compositor devices.  The defaults are no-ops.

>     The clist logic has a few changes.  Since the PDF 1.4 compositor device
>     may use a different process color model from the output device, the number
>     of colorants and the depth (bits per pixel) can be different for the PDF
>     1.4 compositor and the output device.  Thus changes were needed in parts
>     of the clist logic which assumed that these items were constant during the
>     processing of the clist.  An extra field was added to the device halftone
>     to indicate the number of colorants in effect when the device halftone was
>     created.  This data is included when the halftone is serialized for the
>     clist.  (Fortunately the PDF 1.4 compositing does not use halftones or
>     transfer functions.  So the device halftones and transfer functions do
>     not need to be changed when the PDF 1.4 compositor is installed.)

>     As previously mentioned the create compositor procedures for the clist
>     writer and reader now call a couple of compositor specific routines.  These
>     allow the compositor to implement actions related to the clist device.
>     (The PDF 1.4 compositor uses these routines to create the 'write clist'
>     PDF 1.4 compositor and to save and restore the clist device color info.
>     The color_info field of the clist device is changed to match the process
>     color model of the PDF 1.4 compositor while the PDF 1.4 compositor is active.

>     A additional device parameter (PageUsesTransparency) was added.  This
>     parameter is sent by the PDF interpreter to indicate if PDF 1.4 transparency
>     will be used on the page.  The banding/no banding decision and the size
>     of a band includes an estimate of the size of the PDF 1.4 blending buffers
>     if this parameter is true.  Note:  The estimate of the size of the
>     blending buffers is not exact since this calculation is made before the
>     actual number of buffers, the number of blending colors and alpha channels
>     is known.  Fixed values are used for the estimated buffer size.  This is
>     still much better than the pervious situation, in which the only the
>     output raster size was being used.  The blending buffers can easily be
>     30 or more times larger than the raster buffer.

>     This fix also involves the removal of the PDF 1.4 'marking' devices.
>     The marking devices were used to actually implement the pixel marking.
>     The marking devices were created at the start of each high level drawing
>     operation and deleted after the completion of the operation.  The marking
>     device action has been merged into the primary PDF 1.4 compositing device.
>     This change eliminates some device creation overhead.  The overhead would
>     have been worse since most information about high level drawing operations
>     is not passed through the clist.  As a result it would have been necessary
>     to create marking devices for each low level operations.

>     The following issues are not included in this fix but need to be considered.

>     1)  The device filter logic is no longer used.  It may be desired to remove
>     this logic.

>     2)  We currently have a 'create_compositor' device proc.  However there
>     is not a 'delete_compositor' device proc.  As a result, compositor devices
>     can stay in the device chain even when they are no longer needed.  The
>     current fix turns the PDF 1.4 compositor into a 'forwarding' device.  This
>     is the same method used by the overprint compositor device.  I do not like
>     leaving these devices since there is some extra overhead and there may be
>     possible side effects.  (Testing has been done to try to find side effects
>     and none has been found with the current code.)

>     3)  This change only affects devices which can use the clist logic.  This
>     excludes the 'high' level devices.  These include the 'display', 'x11',
>     and 'pdfwrite' devices.  Thus these device will continue to use a full

>     Eliminate a performance problem when a TT font has a large 'loca' table.
>     A fix for 687889 used .sort on the 'loca' table but this takes a long
>     time if the table is large. Only run the .sort if the table is out of
>     order which is rare since the TT font spec requires an in-order table.
>     Bug 687968.

>     DETAILS:

>     Apparently our conversion of the 'japan.ps' file creates a TT font with
>     a loca table that has 20458 entries (even though the original font
>     in japan.ps didn't have that many). This is needed because there are
>     many glyphs that are not present, but we need loca table slots that
>     represent the missing glyphs (same starting offset as next glyph).

>     The time was being spent doing the '{ lt } .sort' of the array  :-(

>     I added logic that checked the order as the loca table was converted
>     to an array so that the .sort could be skipped as long as the table is
>     in order (which it *should* be for a valid TT font). After this change,
>     the HEAD time is 1.16 CPU seconds versus 1.08 seconds for gs8.50.
>     (with the .sort, the time was 257 seconds).

>     I suppose that we could optimize the .sort (put it into 'C') but
>     for now I'll just avoid it most of the time.

>     Note that since the .sort has a procedure callout for the ordering test,
>     it might not speed up that much in 'C'. That's the other reason that it

>     the difference in successive offsets.

>     Note that the PostScript code only needs to deal with the sorted 'locatable'

>     If the .dividesfnts uses a sorted locatable, but doesn't replace the 'loca'
>     table written into the sfnts, then the VMerror occurs because the C code
>     in 'default_get_outline' calculated the glyph_length for the gs_alloc
>     using loca table entries that might be out of order.

>     In order to effect the entire fix, I sorted the 'locatable' for the PS
>     code in .dividesfnts as well as creating a new 'len_glyphs' array in
>     the gs_type42_data structure that holds the actual glyph lengths.
>     The glyph lengths are calculated once when the font is initialized in
>     gs_type42_font_init. If the 'loca' table is in order, then nothing

>     ps2write : Allow ICCBased color spaces when writing a ps2write output.

>     DETAILS :

>     Since CIEBased is not a PDF 1.2 object, we need to convert it somehow.

>     One possible way is to write CIEBased into PDF.
>     We do not choose this way because (1) it will generate an invalid PDF
>     so that we'll not be able to verify the output with PDF readers;
>     (2) we have no code for writing a CIEBased color space to PDF or Postscript,

>     Later we'll need to bring more order to this field.
>     Possibly writing a "restricted PDF1.3" would be better that

>     1. In pdf_copy_color_data, allowed the new value 2 for the parameter for_pattern.
>     In this case non-lossless filters are allowed.

>     2. In gdev_pdf_fill_path, fixed the grouping of clip paths for all
>     meshes|patches of a shading.

>     3. In gdev_pdf_fill_path, used the shading BBox to minimize
>     the size of the raster image.

>     4. In gdevpdfp.c allowed CompatibilityLevel=1.1 .
>     Now this is done mainly for debug purpose,
>     but likely we'll use it in ps2write when the target doesn't handle TT fonts.

>     5. The new function gx_dc_pattern2_get_bbox works for (3).

>     6. The function shade_bbox_transform2fixed has been renamed into
>     gx_dc_pattern2_shade_bbox_transform2fixed with making its scope bigger
>     to work for (5). It has been moved into gsptype2.c,
>     which is mode fundamental than gxshade.c .
>     The following changes happened due to that : gsptype2.c, gsptype2.h,
>     gsshade.c, gxshade.c, gxshade1.c, gxshade4.c.
>     We would like to do more cleanup with replacing it with
>     gx_dc_pattern2_get_bbox, but currently we delay that to simplify this patch.

>     7. Introduced a new field patch_curve_t::straight to know whether a patch
>     boundary is a straight line. patch_fill uses it when passing the
>     shading coverage area.

>     8. mesh_triangle now passes the coverage area.
>     An auxiliary function mesh_triangle_rec is factored out for that.

>     9. patch_fill checks for self-overlapoped patches
>     and prints a warning is the patch appears suspicious.
>     Comments in patch_fill about that have been improved.

>     10. patch_fill and mesh_triangle check the sign odf the coverage area,
>     and change the contour direction for making all contours be positive.
>     This works for proper clipping.

>     11. Fixed compressed streams in opdfread.ps .

>     Implementing a convertion of a shading to a raster image for high level devices.

>     DETAILS :

>     If a high level device can't handle a shading,
>     it is being converted to a raster image.

>     This patch implements it only in OrderResources mode.
>     A generalization to "normal" mode will be done in a separate patch.

>     The generated bitmap sometimes appears too big since it
>     doesn't accout a bbox of a real shading coverage.
>     An optimization is coming soon.

>     1.The device virtual function pattern_manage now handles
>     a new request pattern_manage__shading_area.
>     If it returns 1, the graphics library will pass
>     the shading area as a special call to fill_path,
>     with passing NULL images\r state and NULL clipping path.
>     Such call immediately follows pattern_manage(...., pattern_manage__shading_area).
>     Currently it goes only to a special converter device (see below),
>     other devices and the default implementation return 0
>     for pattern_manage(...., pattern_manage__shading_area).

>     2. A new local type pdf_lcvd_t implements a subclass for
>     memory device, which is used especially for converting shadings
>     to raster image. It is defined locally in pdfwrite.
>     The subcalss redefines 4 device methods :

>     2.1. fill_rectangle with shifting the device space.
>     It is used to mapo the shading and its paths to the image coordinate system.

>     2.2. get_clipping_box returns the target clipping box,
>     to deceive a cut-off condition in the shading algorythm.

>     2.3. pattern_manage returns 1 for pattern_manage__shading_area.

>     2.4. fill_path is used only for handling the shading area.
>     It sets a clipping when instantiating the bitmap.

>     3. gdev_pdf_fill_path implements the convertion with (2).

>     4. gs_shading_fill_path doesn't set up a clipper device
>     when it works with the shading convertion device.
>     Instead that the clipping path is being passed through (2.4).

>     5,. patch_fill in gxshade6.c checks if the devices needs the
>     shading area, and if so, passes the area throuhg the special call to
>     fill_path.

>     for customer #850.

>     DETAILS:

>     The problem was that the DefaultQstate used when making a Pattern
>     was the device *BEFORE* the pdf14 device filter was inserted as
>     the device. If the underlying device had a different 'depth' than
>     the PDF14 device, the pattern cache lookup would always fail which
>     would then cause the fill to return e_RemapColor and perform the
>     PaintProc again. The 'depth' comparison is in gsptype1.c in the
>     gx_pattern_cache_lookup	function.

>     The fix is to set the DefaultQstate *AFTER* the pushpdf14devicefilter
>     is performed (and of course also reset it after popdevicefilter
>     is done).

>     Under special conditions, a CID can be used when the descendant is a Type 3
>     base font. The font's BuildGlyph or BuildChar procedure is invoked to render a
>     character whose code is the last byte originally extracted from the show string.

>     2. copy_glyph_data maintains gs_copied_font_data_s::num_glyphs (gxfcopy.c).

>     3. gs_copied_can_copy_glyphs checks whether the preallocated

>     5. pdf_obtain_font_resource_encoded is changed to handle the case when
>     new glyphs overflow the font copy (gdevpdtt.c).

>     The changes above fix the bug, but we also provide an additional optimization
>     with GLYPHS_SIZE_IS_PRIME 1 (gxfcopy.c):

>     6. Preallocate at least 257 ghyphs rather than 256 ones by the old code;
>     This coners a font of 256 glyphs and 1 .notdef  (gxfcopy.c).

>     7. Use primes numbers for the size of glyphs array instead powers of 2
>     against unprodactive expense of RAM (gxfcopy.c).

>     When the changes 5 was done, a regression happened with tpc2.ps :
>     pdfwrite generated an incorrect PDF. To fix that, we forced to do more changes :

>     8. pdf_register_charproc_font recieved a gs_id of the PS font instead
>     the PDF object id. It caused a problem with multiple muster fonts,
>     because MM instances have same id as the MM font.
>     pdf_encode_string is changed to pass a correct resource id (gdevpdte.c),

>     9. Since tpc2.ps generates hundreds of MM font instances, the field
>     pdf_font_resource_s::u.s.used_fonts may not have a staticly defined size.
>     replaced with a dynamicly allocated array (gdevpdtf.h, gdevpdte.c).

>     10. Garbager descriptor for pdf_font_resource_s is changed to maintain (9).

>     11. A new function pdf_find_resource_by_resource_id is defined for
>     the correct implementation of pdf_used_charproc_fonts (gdevpdfu.c).

>     After it another tpc2.ps regression persisted : the character 'y'
>     dissapperaed in some words. The following changes are done to fix that :

>     12. Improved thge hash function in pdf_add_subset_prefix (gdevpdtb.c).

>     13. Defined FINE_GLYPH_USAGE 1 for a better precision of the font subset,
>     in the case when a PS interpreter callout happens fro CDevProc or for a Type 3 BuildChar
>     (gdevpdfx.h, gdevpdte.c). Currently it works for non-CID fonts only.

>     14. Improved the diagnistics for the missed glyph in a Type 1 font (gs_type1.ps).

>     Actually the last regression reflects another problem in the PDF interpreter,
>     which is described in a new bug 687856.

>     EXPECTED DIFFERENCES :

>     pdfwrite :

>     test-setweightvector.ps
>     tpc2.ps

>     The distilled tpc2.ps gets 1 progression and 1 regression.
>     The progression is the glyph width. The regression is an ununiform
>     stem width while rendering the PDF due to problem in the PDF interpreter.
>     We describe that problem in the new bug 687857.

>     Copies over new-style color procs when making a null device with a
>     target, to avoid inconsistent states. Fixes bug #687770.

>     DETAILS

>     The problem was a null device (for implementing stringwidth) with
>     inconsistent color info; the color_info struct specified 4 components,
>     but the get_color_mapping_procs was
>     gx_default_DevGray_get_color_mapping_procs, which is the desired value
>     for null devices instantiated through gs_copydevice
>     (i.e. -sDEVICE=null). As a result, cm_comps[1] through [3] were left
>     uninitialized, and, when negative, would crash the halftone logic.

>     This patch copies over the new-style color mapping procs (the
>     old-style were already copied) in the gs_make_null_device routine. A
>     strong argument could be made for changing the logic in
>     gx_device_copy_color_procs() instead, but it was felt that this change
>     was more localized.

>     Dan reviewed this patch during a phone conversation, so I am going ahead
>     and committing. I'm also opening a new bug to encourage a closer look
>     at other uses of gx_device_copy_color_procs() to see whether a change
>     there is beneficial or harmful.

>     Fix for Bug 687459 (SEGV) addressing several problems: (i) Elements
>     fetched from a font dictionary have to be dereferenced into a ref
>     since pointers change if the dictionary is resized (to add entries);
>     (ii) The glyph_cache used by gs_font_cid2 fonts needs to be in stable
>     memory since elements might be added after a 'save' and the list will
>     still be refereced by the font, so cannot be freed by 'restore';
>     (iii) The gs_glyph_cache__release was never being called so creating
>     a memory leak -- font notification (called by gs_font_finalize) is
>     now used to free the cache list; (iv) The gs_glyph_cache__release
>     did not work (probably was never tested since it was not being used).

>     DETAILS:

>     Using stable_memory means that the objects created need to be freed
>     properly, that's why the font_notify mechanism was used. This fixes
>     the problem reported by the bug and doesn't seem to have created
>     any other problems (regression test passed).

>     A 'memory' element was added to the gs_glyph_data_s structure so
>     that the 'bits' can be allocated using the desired memory (stable
>     memory in the case that we are using the cache). This was deemed
>     preferable to always using the pfont->memory->stable_memory since
>     changing to this might cause other problems. This did create a
>     fair number of changes since every place the get_outline was used,
>     the glyph_data structure needed to have the 'memory' element set.
>     We could have used 'NULL' to signal pfont->memory, but this might
>     have masked uninitialized memory issues that can be tracked with
>     tools such as valgrind.

>     The gs_glyph_cache__release was totally broken, and since it was
>     not previously used, fixing and testing it presents no risk of
>     other clients relying on broken behaviour.

>     The implementation of the cache is VERY RUDIMENTARY -- a linked
>     list of elements with a hard-coded number (32767) limit to the
>     size of the cache. The size is too small to be useful for Asian
>     fonts, but making it bigger will result in a lot of time spent
>     finding a 'miss' condition. At least the current logic has LRU
>     slot re-use behaviour (which should be retained). Fixing this,
>     and making the cache limit larger are left for a later change
>     (post 8.50 release).

>     Disposition :
>     D1. The PDF spec requires X-compomenent of v-vector always equals to half glyph width.
>     D2. AR5 appears to use W|DW to compute the X-component of the v-vector of WMode 1.

>     The previous patch fixed most problems, but one left unfixed.
>     When a glyph is used with WMode 0, and later with WMode 1,
>     the second usage doesn't store Width and V due to the 'used' flag is already set.
>     This patch introduces 2 separate sets of flags for WNode 0 and WMode 1.

>     Changes :
>     1. Defined a new field 'used2' fro WMode 1 in gdevpdtf.h .
>     2. Allocated the used2 array, provided garbager methods,
>        and a resizing on demand in gdevpdtf.c .
>     3. gdevpdtc.c sets used2.
>     4. Improved the computation of the v-vector in gdevpdtt.c .
>        Now pdf_glyph_widths should be conforming to (D1) and (D2).
>     5. The coordinate adjustment in gdevpdte.c is not longer useful
>        due to (4). Removed.
>     6. When writing W, W2, glyphs are being enumerated with used, used2

>     D2. AR5 appears to use W|DW to compute the X-component of the v-vector of WMode 1.

>     Changes :
>     1. With WMode 1, pdf_obtain_cidfont_widths_arrays obtains both Widths and Widths2 arrays
>        (gdevpdtf.c, gdevpdtf.h, gdevpdtc.c).
>     2. For CID fonts gdevpdtc.c computes both WMode 1 and WMode 2 width
>        when WMode 1 is requested.
>     3. Due to (D1), must compensate the half width when computing a glyph position
>        in gdevpdte.c (hunk #2).
>     4. In gdevpdte.c internal data glyph_origin_shift used opposite signs for
>        CID and non-CID fonts. Now made uniform.
>     5. The Type 0 font matrix and the descendent CID font matrix were applied
>        in a wrong order in gdevpdte.c .
>     6. To satisfy (D2) when WMode 1 is only requested,
>        write DW 0 when WMode 1 is only requested.
>     7. After fixing all above, from the test file of the bug 687753 pdfwrite
>        generated a PDF, which GS failed interpret due to a curious failure
>        with e_dictfull while checking for an absent key /File in the font dictionary.

>     Fix : toolbin/pdfinflt.ps did not decompress some streams.

>     DETAILS :

>     Patch from SaGS for the bug 687746
>     "gs\toolbin\pdfinflt.ps doesn't unpack a stream"

>     Current version of pdfinflt.ps uncompresses only streams that have a single
>     filter applied, and only if that single filter is /FlateDecode. Proposed
>     patch (attached) ads support for procesing streams with multiple filters.

>     However, not all decompressing filters can be removed, and not in all cases
>     it would be desirable to remove them. The /filterstoremove dictionary lists
>     filters that are to be processed, and omits filters that are to be preserved
>     in the output. For streams with multiple filters chained together, the new
>     version of pdfinflt.ps removes all filters from the first in the
>     decompressing chain up to, but excluding, the first filter that is to be
>     preserved. The list of preserved filters, with the reason why these are not
>     removed, follows:

>     /RunLengthDecode, /CCITTFaxDecode, /DCTDecode:
>     These are normaly used for compressing raster images. I assume the main
>     purpose of this tool is to decompress page streams for debugging, and
>     decompressing images only adds a huge amount of binary data, making harder
>     to find and examine content streams. If this is not the case, and getting
>     raw image data is necessary, simply uncomment the lines corresponding to
>     these filters.

>     /JBIG2Decode, /JPXDecode:
>     There's no (standard) PostScript filter that corresponds to these PDF
>     filters. (I think) GhostScript implements these filters in the PostScript
>     interpreter, but not for all platforms, so I added some detection code for
>     them. The preceding paragraph applies too, so I left the lines corresponding
>     to these filters commented out.

>     /Crypt (PDF1.5-specific):
>     This is a generic interface with decryption plug-ins, and has no PostScript

>     The last patch in this series was
>     http://www.ghostscript.com/pipermail/gs-cvs/2004-September/004834.html

>     to remove extended glyph names. We don't like to
>     modify the font, but choose this minimal solution for now.

>     DETAILS:
>     Prior to GS 8, the display device 8-bit native format would use 32

>     tiffsep device fails during device initialization if the size of
>     gx_color_index is 32 bits.

>     This is due to a recent change which made the default number of components for

>     If the bug 687717 is fixed before this patch,

>     DETAILS :

>     Bug 687681 "Character spacing incorrect".
>     The old implementation, which comes from the gs-cjk team,
>     has a bug accessing the replaced metrics of a CIDFontType 0 font,
>     which effectively caused the replaced metric to be ignored with CIDFontType 0 fonts.

>     1. Bug : With CIDFontType 0, CDevProc|Metrics|Metrics2 was searched
>        in the descendent type 1 or 2 font rather than in the parent type 9 font.

>        1.1. A Type 9 font needs to be accessed via a descendent Type 1|2 font
>             in pfont->procs.glyph_info. Added a new field gs_type1_data_s::parent,
>             and provided an access through it with a new function gs_font_parent.

>        1.2. Metrics|Metrics2 is now accessed through gs_font_parent.

>        1.3. To access CDevProc implemented a new function zchar_get_CDevProc,
>             which also works through gs_font_parent.

>        1.4. gs_type1_data_s::parent needs to reset while a type 9 font finalization,
>             due to a reason, which we could not understand for sure.
>             Likely descendent fonts appear to have a bigger lifetime than
>             their parent type 9 font. Probably the descendents are pointed from
>             somewhere besides FDArray (maybe the font registry ?
>             or maybe after scaling the type 9 font from a type 9 copy ?),
>             and we think it's not good.
>             We believe that they should be released together with the type 9 font.
>             For now leaving it as it is, working around with a hack notify_remove_font_type9.

>        1.5. In stable font copies gs_type1_data_s::parent is set to NULL
>             to simplify the finalization. They are not used now.

>     2. Bug : In some cases the glyph bytecode was used instead the CID
>        as a key for searching a Metrics|Metrics2 element (zchar1.c).

>     3. Bug : The PDF interpreter wrongly scaled W,W2,DW,DW2 for CIDFontTYpe0 (pdf_font.ps).

>     4. pdfwrite : Improved the generation of W, W2 for CID fonts,
>        because after implementing (1) re-distilled 401-01.ps rendered incorrectly.

>        4.1. Prefer a non-zero width when computing DW, DW2 (gdevpdtw.c)
>             (debugged with 401-01.ps).

>        4.2. Don't skip zero W, W2 elements. The old code recognized zeros as
>             unused glyphs, but must do with the real glyph set in the font copy
>             (debugged with the test file of the bug 687681).

>     5. zcharstring_outline still ignores CDevProc. We believe that it is correct,
>        because it is used to compute font features with no dependence on
>        the relaced metrics.

>     6. pdfwrite : Allowed a CDevProc callout for CIDFontType 0, because
>        pdfwrite needs to know replaced widths, as well as it was done a half year ago
>        for CIDFontType2. Actually after implementing (1) pdfwrite stopped
>        to work correctly when re-distilling a PDF file with CIDFontType0,
>        due to now it uses W,W2,DW,DW2.

>        6.1. A new function z1_set_cache is defined for this purpose
>             similarly to zchar42_set_cache.

>        6.2. gs_font_procs::glyph_outline now retrieves the side bearing and width.
>             Added a new argument 'sbw' to all implementations.

>           6.2.1. Currently this function extension is implemented for charstring fonts only,
>               which need to interpret a charstring to retrieve the info :
>               type 1,2,9, because we don't want to run the type 1 interpreter 2 times
>               for getting sbw and bbox. Other font types retrieve zeros,
>               which currently are not used.

>           6.2.2. type1_cis_get_metrics has been made public.

>     7. We believe that the implementation of W,W2,DW,DW2 in the PDF interpreter,
>        which was contributed by the gs-cjk team, is unreasonably overcomplicated,
>        because it is based on CDevProc, which needs an interpreter callout,
>        which appears extremily hard from pdfwrite.
>        For now leaving it as it is (except a small improvement in (3)).
>        We would like to generate Metrics, Metrics2 instead that.
>        Note that a small part of this patch (the part (1)) is necessary
>        for generating Metrics, Metrics2 for CIDFontTYpe 0.

>     DETAILS:

>     Three problems have been found with this file.

>     The rangecheck is actually a secondary effect.  The actual problem
>     was a typecheck in setrgbcolor.  However that error occurred inside
>     a stopped context.

>     1) The file has a mask group.  This group specifies a color space (CS).
>     The previous code set the current color space to the given value.
>     However the FillColorSpace and StrokeColorSpace were not set.  As a
>     result, a DeviceRGB color space was being used instead of the specified
>     DeviceGray color space.  This resulted in a mismatch in the number
>     of operands when the color as set (1 versus 3).  The fix consists of
>     setting both StrokeColorSpace and FillColorSpace when a mask group
>     contains a CS value.

>     2) The file uses scn for setting color values for a DeviceGray color
>     space.  FillColor and StrokeColor can contain wither a single numeric
>     value (which is common but not required for DeviceGray) or an array
>     of values for all other color spaces.  The scn and SCN operators were
>     always assuming that these values always contained arrays.  The fix
>     consists of checking for the non array cases in the operators.

>     Bug 687672  "incorrect font rendering".

>     An Encoding may specify various character codes for same glyph, and
>     Widths may specify different widths for those codes.
>     Thus same glyph may be used with different widths.

>     This patch continues a long story about the handling of different widths for same glyph,
>     which includes my old hacks (pdf_font.ps Revision 1.22 and 1.26)
>     and Alex's change pdf_font.ps Revision 1.57 .
>     Alex defines new glyph names for same glyph to resolve the widths conflict.
>     After the Alex's change my old hacks appear low useful, and can be removed.

>     This patch
>     1. Removes the hacks;
>     2. Improves the Alex's change with the case when CharStrings has no referred glyph
>        (debugged with 1_2001.pdf)

>     Fix (Type 1 hinter) : A further improvement of the glyph rendering quality, step 1.

>     DETAILS :

>     This change is algorithmically equivalent,
>     because new code is disabled wirth configuration switches
>     listed below.

>     1. FINE_STEM_COMPLEXES
>        1.1. Stem complex could miss a common boundary.
>        1.2. Stem width could be distorsed due to a common boundary missing
>             (Bug 687578 "T1 hinter disturbs stem width".).
>        1.3. Overall hint (if presents) should have a bigger priority.
>     2. ALIGN_BY_STEM_MIDDLE
>        2.1. A stem middle could be shifted too much due to
>             independent grid-fitting of boundaries and the change 1.2 -
>             see 'i' in ccc-.pdf attached to Bug 687578.
>             Fixed with an improved alignment with t1_hinter__align_stem_to_grid.
>        2.2. This isn't applicable for top|bottom zones from the TT stem recognizer,
>             because we want to force outer boundaries to keep the glyph height.
>        2.3. 033-52-5873.pdf defines "pseodo-stem" hints,
>             which have only one boundary corresponding to real poles.
>             recognize them with t1_hinter__mark_existing_stems,
>             and don't apply the improved alignment,
>             because those stems designate outer glyph boundaries,
>             which we want to force the uniform glyph height.
>             Apparently fixes Bug 687579 "Type 1 hinter disturbs glyph height".
>     3. OPPOSITE_STEM_COORD_BUG_FIX
>        Aligning a stem width, the resolutions by X and Y were exchenged.
>     4. TT_AUTOHINT_TOPZONE_BUG_FIX
>        topzone and botzone were mixed when come from the TT stem recognizer.

>     Also improved general comments in gxhintn.c .

>     EXPECTED DIFFERENCES :

>     Fix for 687640 Unable to set default halftones for PDF.

>     DETAILS:

>     To support both PS level 1 and PS level 2 interpreting modes,
>     Ghostscript defines two routines for setting a default halftone.
>     PS level 1 does not support resources.  Thus for PS 1 we have
>     .setdefaultscreen which sets a default halftone which is defined
>     inside of gs_init.ps.  For PS 2, we have .setdefaulthalftone
>     which is similar to .setdefaultscreen except that it also checks
>     for a default halftone resource.

>     The PDF interpreter's handler for the /HT gstate parameter
>     called .setdefaultscreen if the parameter value was /Default.
>     This fix changes the handler to use .setdefaulthalftone instead.
>     This results in the PDF interpreter using the default halftone
>     resource if it is present.

>     Addition of a Library Context to start the process of removing globals.

>     DETAILS :

>     The goals is to remove globals from the system, this includes static
>     globals that would hinder multiple threads from running at once.

>     gs_lib_ctx is intended to be used as the opaque "handle" object
>     that a client would use to associate with a thread running through
>     the library.  Independent of a gs or a language switch build, this
>     needs a new iapi2.h that allows the use of better job control from the
>     client side.

>     gs_lib_ctx is stashed under the gs_memory_t object and all memory objects
>     used by a thread refer to the same gs_lib_ctx.  This storage location was
>     choosen as a convenence since a memory_t pointer is common throughout the
>     system.  Most of the turmoil is adding memory_t pointers to functions that
>     used global variables but didn't have a memory pointer.

>     FILE stdin, stdout, stderr are one per process by default.
>     stdin and stdout may be changed but stderr may not.
>     FILE stderr is one per process and shouldn't be changed.
>     Note the stderr_fn is also one per process, changing this function pointer
>     will not help as most users of stderr printing do not have a thread handle.
>     Changing to a thread local storage mechanism can solve this.

>     gs_id's  are currently per thread with each thread starting over at  1.
>     This can be moved to per process with mutexes if so desired.

>     A library context has a pointer to the top_of_system the intent is that this
>     a void handle avaliable to make top of the system calls without knowing the
>     data type.  In a postscript only  build this would be gs_main_instance but
>     in a language switched build this would be an object above that main_universe.

>     Other members of gs_lib_ctx_t are nothing more than global objects relocated
>     to this "bag".  gs_name_table, dict_autoexpand  are examples of this.  There
>     are a few more globals that will be moved.

>     At the moment iapi is still constrained to one thread, since some of the
>     globals haven't been removed yet.

>     The display device's callback function setting is supported for now
>     but this interface should be changed to a sDEVICE style call.

>     gs_memory_t is the base type the abstract type gs_raw_memory_t is gone,
>     this means that all memory types must derive from gs_memory_t.
>     In addition to a pointer to the gs_lib_ctx there is a pointer to a
>     non_gc_memory this will always point to a non garbage collected memory,
>     it maybe the current object or an object below the current gargabe
>     collected memory space.  This can be used were the previous code
>     used the global gs_malloc_memory.  gs_malloc() now takes a memory pointer,
>     it finds the non-gc memory from a valid memory pointer and allocates from it.

>     We received a posting against 687551.  This posting indicated that some
>     files in arXiv.org were failing with the current version of Ghostscript
>     but worked with older versions.  The files were all created by a package
>     called Canvas by Deneba Systems.  They failed because setcmykoverprint
>     was not defined.

>     Evidently the people at Deneba Systems did not read the following comment
>     from page 15 of TN 5044:

>     "Note The setcmykoverprint operator has not been adopted by the industry.
>     It remains on the list of color convention operators because it has some
>     perceived usefulness, but it is not supported by any shipping host-based
>     separation applications today."

>     The even stranger detail is that the Deneba Systems people have a
>     dummy version of this procedure that does not implement overprinting.
>     Thus if they do not need overprinting, they have no need to use this
>     procedure.

>     The files also fail with Distiller 6.0, Illustrator CS, and Photoshop 6.0.
>     However this change allows these files to work with current Ghostscript.

>     The change consists of putting in a dummy version of the setcmykoverprint

>     DETAILS :

>     Bug 687594 "Barcode Width".
>     See comments in the new code.

>     This solution is a partial one.
>     With the current architecture of the Postscript interpreter,
>     a device can't recognize whether a PS charproc sets line parameters or not.
>     Therefore we copy to PDF the values, which appear at a first use
>     within a charproc. The old code copied only values, which differ from defaults.
>     The new behavior appears closer to Adobe Distiller.

>     A complete solution should copy the PS behavior to PDF,
>     i.e. the PDF charproc should set those and only those parameters,
>     which are set by the PS charproc. For doing that we need flags in the graphic state structure
>     per each graphic state parameter, reset all them before running a charproc,
>     and set whenever a parameter is changed. Without the flag, when the charproc sets
>     a value equal to the old one (which was inherited from the context of
>     the glyph usage), the event of setting is lost and causes a line width and other problems.
>     We don't want such a deep change now, and go with the partial solution,
>     because the partial solution appears enough for customer's needs.
>     Likely Adobe Distiller have same architectural problem, and resolves it in same manner.

>     Fix to pdfwrite initialization to make sure initial distiller params are

>     DETAILS:

>     Earlier change to use .putdeviceparamsonly in gs_pdfwr.ps so that the
>     use of setdistillerparams does not reinitialize the device caused the
>     initial parameter settings to not be set in the device. The change to
>     gs_pdfwr.ps accomplishes this.

>     Part of the investigation by Igor Melichev discovered that the values of
>     disillerparams would not be correctly reflected in the pagedevice. The
>     change to gs_setpd.ps collects the currentdistillerparams when the device
>     is pdfwrite and merges new values into the pagedevice dictionary. The
>     method is similar to that used for the dynamicppkeys such as PageCount

>     Fix for 687565 Incorrect equiv color for Orange in Altona test file.
>     The altona test file Altona_Visual_bb_1v1_x3.pdf contains a spot color
>     called Orange.  An incorrect equivalent CMYK color is being determined for
>     this spot color.  The result is that the spot color is being displayed as
>     black for the devices which handle spot colors and attempt to determine
>     equivalent CMYK colors for the spot colors.  These are the psdcmyk,
>     tiffsep, and display (with -dDisplayFormat=16#a0800) devices.

>     DETAILS:

>     The Orange spot color is used in two different DeviceN color spaces.  The
>     first color space has components named 'None'.  These components are used
>     as part of a special feature described in section 4.5 of the PDF 1.5 spec.
>     This feature uses the None components as a means for passing values to
>     the color space's alternate tint transform function.  In the example in
>     the spec., these values are an equivalent color in the alternate color
>     space.

>     Our logic for determining an equivalent CMYK color for a spot colorant
>     sets all color components except for the desired spot color to zero and
>     then uses the tint transform function to form an alternate color.  This
>     results in the equivalent CMYK color being black since the None values
>     contain the real information for the tint transform function.

>     This change consists of check for the presence of DeviceN color space
>     components named None.  If any are detected then the equivalent CMYK
>     color logic exits rather than determine an invalid color.  This is
>     sufficient for this case since the second color space which contains
>     the Orange spot color does not have the None components.  For the
>     general case, a solution needs to be found which samples colors given
>     actual values for the None components.

>     parameter is specified then a rangecheck can occur.  This happens when
>     the halftone includes two or more colorants that are not in the

>     The problem occurs because the get_color_comp_index device procs use

>     This change implements the enhancements described in 542629 CMYK
>     tiff driver and 687440 Support for outputting PDF separations
>     separately.  This change implements three devices:  tiffgray
>     which produces an 8 bit gray output with uncompressed data,
>     tiff32nc which produces 32 bit CMYK with uncompressed data, and
>     tiffsep which produces a tiffgray file for each separation
>     (CMYK and spot colors) and it also produces a CMYK output file
>     which is created using the CMYK image data plus the spot
>     colors image data.  The spot colors are converted to CMYK using
>     the logic in 687431.

>     DETAILS:

>     This change requires that 687504 be included in the sources.

>     The tiffgray and tiff32nc devices are logically similar to the
>     tiff24nc device except for the use of gray and CMYK process
>     color models.

>     The tiffsep device uses much of the logic which has been created
>     for the psdcmyk and spotcmyk devices.  These include logic for
>     implementing the SeparationOrder setpagedevice parameter 687423,
>     logic for determining an equivalent CMYK color to spot colors
>     687431, and automatically detecting spot colors (without requiring
>     that they be specified via the SeparationColorNames setpagedevice
>     parameter 687504.

>     The tiffsep device also prints the names of any spot colors
>     detected within a document to stderr.  (stderr is also use for the
>     output from the bbox device.)  For each spot color the name of
>     the color is printed preceded by '%%SeparationName:  '.  This
>     provides a mechanism for external applications to be informed about
>     the names of spot colors with a document.

>     Due to the 64 bit pixel size limitation, the tiffsep can handle
>     a maximum of 8 colorants per pass.  However it is possible to
>     handle more than 8 colorants by doing multiple passes.  For each
>     pass after the first one, the names of all of the separations need
>     to be specified via the SeparationColorNames parameter and the
>     names of the desired separations need to be specified via the
>     SeparationOrder parameter.  When colorants are selected via the
>     SeparationOrder parameter, the composite CMYK output contains
>     the equivalent CMYK data only from the selected colorants.  It is
>     possible to create an overall CMYK composite for more than 8
>     colorants by then adding together (via an external application like
>     imagemagick) the composite CMYK output files from the individual
>     Ghostscript passes.

>     Internally each spot color is assigned a spot color number.  These
>     numbers start with 0 for the first spot color.  The spot color
>     numbers are assigned in the same order as the names are printed to
>     stderr (see above).  This order also matches the ordering in the
>     SeparationColorNames list, if this parameter is specified.  The
>     spot color numbers are not affected by the SeparationOrder parameter.

>     This device creates multiple output files.  The file specified
>     via the OutputFile command line parameter is used to contain the
>     composite CMYK equivalent.  File names for the separations for the
>     CMYK planes are created by appending '.Cyan.tif', '.Magenta.tif'
>     '.Yellow.tif' or '.Black.tif' to the to the end of the file name
>     specified via the OutputFile parameter.  File names for the spot
>     color separation files are created by appending '.sn.tif' (where n
>     is the spot color number) to the end of the file name specified via
>     the OutputFile parameter.

>     The src/gdevtsep.c source file does have a compile time option for
>     including/not the '.tif' at the end of the created file name.  It
>     also has a compile time option for using the name of the spot color
>     as part of the file name.  However this is not enabled since there
>     may be conflicts with spot color names (in which Adobe allows almost
>     anything) and the operating system's conventions on file naming.

>     This change consists of the new source module src/gdevtsep.c,

>     Fix for 687534 Unable to determine equivalent CMYK for spot colors
>     that are only used with overprint.

>     DETAILS:

>     The given test file uses spot colors.  However the psdcmyk device
>     was creating output files which did not contain equivalent CMYK
>     colors for the spot colors.  The cause was that the previous
>     version of the logic was capturing the equivalent CMYK colors
>     when the psdcmyk device's high drawing procs were called.  However
>     if overprinting is enabled, then the overprint device was inserting
>     its own versions of these routines.  Since it only took one call
>     to a high level drawing handler, the previous logic would capture
>     the equivalent CMYK colors if there were any drawing operations
>     with a spot color that did not have overprinting enabled.

>     The fix consists of moving the capturing of the equivalent CMYK
>     colors to a new device proc.  This new device proc is called
>     update_spot_equivalent_colors.  This device proc is called whenever
>     a Separation or a DeviceN color space is installed.

>     The default version of the proc does nothing.  Thus there is only
>     a small amount of overhead added for the installation of Separation
>     and DeviceN color spaces for devices which do not need the equivalent
>     CMYK colors for spot colors.

>     Most of the change consists of the standard details of adding a
>     new device proc.  There are several places that have to be updated
>     when this is done.  The documentation in doc/Drivers.htm was updated
>     to include this new proc.  The high level drawing handlers in the
>     psdcmyk devices were removed and a new psd_update_spot_equivalent_colors
>     procedure was added.  Some minor changes were made in the logic in
>     gsequivc.c since it is no longer necessary to scan through base and
>     alternate color spaces looking for Separation and DeviceN color spaces.

>     687504 Enhancement: Imaging spot colors without using the
>     SeparationColorNames parameter.

>     DETAILS:

>     The purpose of this enhancement is to provide an example of how
>     to implement imaging spot colors without requiring that they be
>     specified in advance via the SeparationColorNames setpagedevice
>     parameter.  Note:  Spot colors are only supported on a few devices
>     which have output file formats which allow for spot colors.  These
>     are currently the psdcmyk, spotcmyk, and xcfcmyk devices.

>     This commit only implements this feature on the psdcmyk, spotcmyk
>     and devicen devices.

>     In order to implement this feature, a device needs to be able to
>     allocate image buffer memory for each colorant and to detect when
>     a new colorant is being used inside of a color space.  The
>     implementation has the following pieces:

>     1.  The handling of the MaxSeparation setpagedevice parameter was
>     extended.  Previously this parameter was always set to one.  For
>     most devices it now indicates the number of colorants being used
>     by the device.  For most devices this is a fixed quantity, however
>     for the psdcmyk device, this parameter can be used to tell the
>     device to allocate image buffer memory for up to eight colorants.
>     (The eight colorant limit is due to the fact that the psdcmyk
>     device uses 8 bits per colorant and we currently have a 64 bit
>     maximum pixel size.)

>     2.  The devices already have a 'get_color_comp_index' routine which
>     is used to query if a colorant is supported by the device.  However
>     this routine is used for both real components in color spaces and also
>     for some special cases.  For instance, the same halftone may be used
>     either for a cyan or a red colorant.  To handle this case, the halftoning
>     setup logic will query the get_color_comp_index routine to check if
>     cyan is supported by the device.  If not then a query is made to see
>     if the device supports red.  By monitoring the names of the components
>     passed to get_color_comp_index routine, a device can detect when a new spot
>     color is being used.  However it is necessary to be able to detect
>     the special cases so that the device does not believe that it has a
>     'red' spot color.  To do this the third parameter of the
>     get_color_comp_index device proc was logically modified to indicate
>     if a name represents a name actually in a color space or one of the
>     special case situations.  Previously this parameter was not being used.

>     3.  The get_color_comp_index routine for the psdcmyk device was
>     modified to look for new spot colors and to add then to its list of
>     colorants if there was space available.  Note:  This also required
>     that the psdcmyk device have its own structure descriptor, pointer
>     enumeration and relocation procedures.  The macro which was used to
>     define the psdcmyk and psdrgb devices needed to be changed since the
>     previous macro used the st_device_printer structure descriptor instead
>     of the new structure descriptor for the psd devices.

>     1.
>     The test file of the bug 687419 shows that we had 3

>     - the analigned glyph origin;
>     - uniform glyph size;
>     - and contrast stems.

>     This also reduces the number of glyph raster variants in the cache.

>     2.
>     The old interpolation algorithm could cause
>     significant distortions with flex-like serifs, which are not marked with flex.
>     The character 'L' in the test document of the bug 687419 demonstrates that.
>     If the path goes outside the interpolation interval
>     and have no turns, now we shift the "outer" parts rather than
>     breaking the path at extremal poles. (We wanted this change
>     a long ago but haven't got a strong reason for it.)

>     The threshold in t1_hinter__is_stem_hint_applicable changed from

>     Debugged with comparefiles/tpc2.ps .

>     5. In the test file of the bug 687419 the small font has no
>     upper alignment zone for lowercase. This caused an uniform glyph height
>     due to wide and norrow horizontal stems aligned ocasionally

>     The list of changes includes:

>     1.  Added logic to check_device_separable to also set the gray_index
>     value.  This suggestion came from Russell Lang.

>     2.  Add verification that a colorants bits are consecutive.  (from
>     Russell Lang in:
>     http://www.ghostscript.com/pipermail/gs-code-review/2004-May/004501.html

>     3.  Changes to gx_default_encode_color and gx_default_decode_color
>     to use position and bit count info from the device's color_info data.
>     (Also from Russell Lang in the previously mentioned submission.)
>     (See the comments in item 21 below about the gx_default_decode_color
>     routine.)

>     4.  Included test routines. (Also from Russell Lang in the previously
>     mentioned submission.)

>     5.  Added calls to check_device_separable prior to calls to the
>     various 'fill_in_procs' routines (gx_device_fill_in_procs,
>     gx_forward_fill_in_procs, fill_in_procs).  The fill_in_procs routines
>     use the separable information in choosing default routines for
>     the encode_color and decode_color routines.  Thus we have a chicken
>     and egg problem since check_device_separable also uses the device's
>     encode_color routine.  The test routines from Russell were a great
>     help in debugging

>     Also various changes that were found while testing this patch:

>     6.  The various color deskjet drivers (gdevcdj.c) was incorrectly setting
>     the dither_grays and dither_colors values to 5 instead of 256.  (I
>     have no idea why.)  The max_gray and max_color values were set to
>     being set correctly to 255.

>     7.  The color deskjet devices (gdevcdj.c) were doing BG and UCR
>     removal inside of the encode_color routines.  These devices use the
>     default color_mapping_procs which also do these tasks.  The code in
>     the encode_color_routine was removed since it could cause conflicts
>     with the overprint routines.  The code in the encode_color routine
>     was also using a fixed BG/UCR logic (from PS level 2).

>     8.  Corrected a problem in the color desk jet decode_color routine
>     which was always returning zero for the black value.

>     9.  Changed the casting for values assigned to the std_colorant_names
>     field.  Note:  MSVC and gcc complain about different conditions.
>     There does not seem to be a combination that will keep both happy.
>     This set produces no complaints from gcc.

>     10.  Corrected the setting of dither_grays and dither_colors for the
>     devicen device.  Previously this was being set to 1 when it should have
>     been set to 256.  Found by Russell Lang.

>     11.  Modified check_device_separable to only check for appropriate
>     values of the max_gray/dither_grays and max_color/dither_colors
>     pairs only for gray/color devices.

>     12.  Added check for encode_color routines which encode zero
>     bits for a colorant.  Previously this condition would have caused
>     an infinitely in check_device_separable.  Change suggested by
>     Russell Lang.

>     13.  Removed a previous call to set_linear_color_bits_mask_shift
>     in gx_default_fill_in_procs.  This has been logically replaced by
>     the calls to check_device_separable which have been added.

>     14.  Corrected a problem in the ppm_map_rgb_color in gdevpbm.c.

>     the dither_grays and dither_colors values.

>     16.  Removed the check_process_color_names routine from gdevpsd.c
>     since it not used.

>     17.  Modified the dci_alpha_values macro in gxdevcli.h.  This
>     macro was setting some devices as 'separable' but was not setting
>     the related color_info fields (comp_shift, comp_bits, comp_mask).
>     Now this macro sets a devices as 'unknown'.  The check_device_separable
>     routine will change this for devices which are separable.  Devices
>     which want to change their process color model need to either set
>     themselves as 'unknown' and let check_device_separable handle things
>     or else the device needs to setup its own values for separable
>     color_info fields.

>     18.  Added a call to check_device_separable into gdev_x_open in
>     gdevxini.c.  With this addition, the x11 device is detected as being
>     sperable.  This is need since the x11 device sets up a color map in
>     gdev_x_open.  Prior to this, the encode_color routine for he x11 device
>     returns 0 regardless of its input.

>     19.  Modified the uniprint device (gdevupd.c) and color laser jet
>     devices (gdevcljc.) to use 256 instead of 5 for its dither_gray and
>     dither_color values with devices that have 8 bits per colorant.  This
>     is appropriate since the the max_gray and max_color values are 255.
>     (I do not know why these values were being set to 5.  This same error
>     was found in gdevcdj.c.  My only guess is that it was a typo in gdevcdj.c.
>     Since this device is recommended as an example of how to code a color
>     raster device (in Devices.htm), the error was propogated into the
>     other devices.

>     20.  Added more comments to gxdevcli.h explaining the use of the
>     gray_index, max_gray, dither_grays, max_color, and dither_colors
>     fields in the device color_info structure.

>     21.  Changed the gx_default_decode_color routine (again).  Russell
>     Lang created two revisions to this routine as part of his efforts on
>     this task.  However one version was slow but produced the desired
>     results.  The second version was faster but its output was slightly
>     different.  This revision produces the same output as the first
>     version but does so without the while loops that slowed its operation.

>     Note:  There is another related submission from Russell Lang that is

>     Fix (pdfwrite) : Add Encoding element even if the font has no glyph.

>     DETAILS :

>     Debugged with the test file of the bug 687464
>     "Problem converting from PS to PDF. 2 latin characters did not convert properly." :
>     different PDFs generated with URW fonts and with Soft Horizon fonts
>     rather none of them were embeded.

>     The old code did not add a glyph to Encoding if the PS font has no glyph defined.
>     Due to that, if the source encoding uses an instand glyph,
>     the instandard glyph was not written to Differences,
>     causing a standard glyph erroneusely appeared instead the instandard glyph.
>     With this patch an Encoding element and a ToUnicode element are created in any case :
>     either the glyph is defined in the PS font, or not.

>     DETAILS:

>     The jasper library also ships with an autoconf build framework for POSIX
>     systems. Unfortunately, it relies on this framework to generate a header
>     file with defines describing the local system. This header, located in
>     jasper/src/libjasper/include/jas_config.h can be generated by hand from
>     the jas_config.h.in template, but it must be available when we're directly
>     compiling the source as part of Ghostscript.

>     We could attempt to construct one of our own, but within the confines
>     of an autoconf build, using jasper's native configure is more robust.
>     We could also go ahead and use recursive make to build the library
>     natively, but we would need a static makefile for non-autoconf builds.

>     Jasper provides an alternate header, jas_config2.h for use with MSVC.

>        This complies the color approximation with the specified smoothness.
>     2. Skipped quadrangles and triangles outside the clipping area.

>     The old implementation of the radial shading extensions appears
>     incompatible with the tensor representation of the radial shading

>     Fix for 687418 WTS does not work with bitcmyk driver.  This fix
>     is applicable to most devices.

>     DETAILS:

>     WTS screening, overprinting, halftoning for more than five colorants
>     and the fast halftoning logic need to be able to create gx_color_index
>     values without using the encode_color routine.  This only works if a
>     device is 'separable'.  However, by default, most devices indicate
>     'unknown'.  This change implements a heuristic for checking if a
>     device is separable.  If so then it also determines the various
>     related parameter values (comp_shift, comp_bits, comp_mask).

>     Implement 687423  Implement SeparationOrder for psdcmyk device.

>     DETAILS:

>     The following changes are for implementing the SeparationOrder
>     parameter for the psdcmyk device.

>     The change consists of the following:

>     1.  Several routines which were duplicated in the spotcmyk
>     and psdcmyk devices were restructured to allow the use of
>     common subroutines.  As part of this effort the various
>     common DeviceN related parameters were separated into a
>     substructure (call devn_params).  This allows the use of
>     common routines even though the devices do not have the
>     same overall device description structure.

>     2.  Changes to the src/gdevpsd.c module for actually collecting
>     the SeparationOrder parameter data and then using it.  Note:
>     The treatment of separations is different for the process
>     color model colorants versus the spot colors.  The colorants for
>     the process color model do not have their order changed.  The
>     output file always starts with information for the CMYK channels.
>     If one of these colorants is not specified in the SeparationOrder,
>     then the output channel data in the file will simply be 'blank'.
>     Spot colors follow CMYK data.  They are rearranged.  Only the
>     spot colors specified are output.

>     3.  Several checks in src/gdevdflt.c and src/gxcmap.c had to
>     be removed or modified.  These checks were assuming that a
>     device with a single component uses a gray process color
>     model and a device with three components used RGB.

>     1. The "uninitialized data" warning in alloc_name_index_is_since_save
>     in isave.c was a real bug with an indeterministic behavior :
>     nref.tas.rsize was accessed by names_index_inline from names_string_inline

>     occurs when dithering on devices which use a 256 color palette.

>     DETAILS

>     The halftoning logic assumes that there are the same number
>     of shades of each color.  However the 256 color palette
>     devices were using a 7x7x5 color cube.  I.e. there were 7
>     shades of red and green, however there were only 5 shades of
>     blue.  The data in the device's color_info (max_color, max_gray,
>     dither_colors, and dither_grays) indicated that there were
>     7 shades.  The halftoning logic, using this information, was
>     attempting to display the given pale yellow color by dithering

>     encode_color routine returned colors which include solid blue
>     for all cases.  This biased the resulting halftoned color
>     toward blue.

>     The fix involves changing the 256 color palette devices to
>     use a 6x6x6 color cube.  The same routine pc_8bit_map_rgb_color
>     is used for all of the 256 color palette devices.  Thus the
>     change consists of modifying this routine and the associated
>     pc_8bit_map_color_rgb routine.  The specification of each of

>     Fixes Bug #687288 for customer #32.

>     DETAILS:

>     The scaling difference in the annotation (object 14 0) was due to

>     Implementing current point with double precision.

>     DETAILS :

>     The old code stores the current point in pgs->ppath->position
>     with the 'fixed' representation in the device space coordinates.
>     This appears insufficiently precise if a document constructs a path
>     with multiple 'rlineto' or 'rcurveto'. A significant to error accumulation happens.

>     We implement the current point with 'double', duplicating pgs->ppath->position
>     with the new field gs_imager_state::current_point.
>     We can't replace pgs->ppath->position with the new one due to several reasons :

>     - Sometimes (in the text processing, in arc processing and in reversepath)
>       a new current point is computed when imager state is not accessible.
>     - Don't want to spend processor time for conversion double to fixed,
>       whenever a fixed is needed.
>     - Don't want to modify many of low level modules;

>     Text operation always round the current point to 'fixed'.
>     Note that the convertion from fixed to double is always precise,
>     therefore we widely use it with text operations.

>     Thus this improves the precision of moveto, lineto, curveto,
>     rmoveto, rlineto, rcurveto, but the precision of other operators
>     left as it was. Likely there is no strong need to improve text operations
>     due to pixel rounding, but it would be useful to improve arc, arcn, arct, arcto.
>     However an improvement of arc operations isn't a high priority,
>     and after this patch becomes a local change.

>     We removed ppath->outside_position, because
>     pgs->current_point now effectively handles this feature.
>     Due to that the rounded pgs->current_point may be unequal to pgs->ppath->position
>     when the current point is outside the range.

>     The configuration flag PRECISE_CURRENTPOINT defined in gxstate.h
>     helps to debug the new code with raster comparizon with the old code.
>     PRECISE_CURRENTPOINT 0 works same as the old code except the
>     coordinate clamping. Therefore once tested with the comparison,
>     the further validation reduced to a validation of the code
>     swtched by the flag - this part pof code is pretty small.

>     The mode (PRECISE_CURRENTPOINT 0) **MUST**NOT** go to production
>     due to the dropped clamping. PRECISE_CURRENTPOINT 1 handles the clamping.

>     Implementation of 687326 Enhancement: Handling of PDF 1.5encryption.

>     DETAILS:

>     The PDF 1.5 specification has added several some features for
>     encryption of PDF documents.

>     1.  The new encryption changes are indicated by a /R value of
>     4 in the Encryption dictionary.  Note:  The encryption algorithm
>     is the same as /R = 3.

>     2.  The encryption handling for strings and streams may now be
>     specified independently.  Current possibilities are 'Identity'
>     and the standard handler.

>     Note:  There are more encryption features in the PDF 1.5 specification.
>     HowevertThe only means that I have for generating test files for these
>     new encryption features is Acrobat 6.0.  This patch will decode files
>     which are encrypted using Acrobat 6.0.  There is one more feature
>     (EncryptMetaData) which will be the subject of a separate patch.
>     Between the features covered by the current patch and the EncryptMetaData
>     patch, this includes all of the capabilities that are available to a user
>     of Acrobat 6.0.  Since Acrobat 6.0 is the major producer of files with
>     these new encryption features, Ghostscript will have the ability to
>     decrypt files which we are likely to see in the near future.

>     from being washed out.

>     While binary compatibility was maintained, and we link just fine to a

>     Improving the filling algorithm, step D6.

>     DETAILS :

>     The algorithm for for filling an individual trapezoid
>     used a wrong formula when rounding a coordinate to pixel index.

>     An intersection of a trapezoid boundary with a scanline
>     is represented as a rational value, in which the fraction
>     represent a part of an unit of 'fixed'.
>     Computing a pixel index, the fraction was ignored.
>     Due to that the spot sides were biased into about 1/256 pixels.

>     The bias appears important when some trapezoids are fixed with
>     swapped coordinate axes, because the bias appears in an opposite
>     direction to one with unswapped axes. Therefore a decomposition
>     of a shading missed pixels, which fall exactly into the biased
>     boundary, causing a dropout.

>     Here is the analyzis of the old rounding :

>     We must paint pixels with index i such that

>         Xl <= i + 0.5 < Xr

>     The condition is is equivalent to

>         Xl - 0.5 <= i < Xr - 0.5

>     which is equivalent to

>         (is_integer(Xl - 0.5) ? Xl - 0.5 : ceil(Xl - 0.5)) <= i <
>         (is_integer(Xr - 0.5) ? Xr - 0.5 : floor(Xr - 0.5) + 1)

>     (the last '+1" happens due to the strong comparizon '<')
>     which is equivalent to

>         ceil(Xl - 0.5) <= i < ceil(Xr - 0.5)

>     trap_line represents the intersectiion coordinate as a rational value :

>         Xl = xl + e - fl
>         Xr = xr + e - fr

>     gxdtfill.c computes l.x = x0l + (fixed_half - fixed_epsilon).
>     In our notation it is equal to :

>         xl' := xl + 0.5 - e
>         xr' := xr + 0.5 - e

>     Then

>         xl = xl' - 0.5 + e
>         xr = xr' - 0.5 + e

>         Xl = xl' - 0.5 + 2e - fl
>         Xr = xr' - 0.5 + 2e - fr

>         ceil(xl' - 0.5 + 2e - fl - 0.5) <= i < ceil(xr' - 0.5 + 2e - fr - 0.5)

>     which is equivalent to

>         ceil(xl' + 2e - fl) - 1 <= i < ceil(xr' + 2e - fr) - 1

>     We have :

>         ceil(xl' + 2e - fl) - 1 ==

>         (is_integer(xl' + 2e - fl) ? xl' + 2e - fl - 1 : ceil(xl' + 2e - fl) - 1) ==

>         (is_integer(xl' + 2e - fl) ? xl' + 2e - fl - 1 : floor(xl' + 2e - fl))

>     Since -e <= fl < 0, it is equal to

>         (is_integer(xl' + e) && e == fl ? xl' + 2e - fl - 1 : floor(xl' + 2e - fl)) ==

>         (is_integer(xl' + e) && e == fl ? xl' + e - 1 :
>          is_integer(xl' + e) && e != fl ? floor(xl' + 2e - fl)
>         !is_integer(xl' + e) && e != fl ? floor(xl' + 2e - fl)
>         !is_integer(xl' + e) && e == fl ? floor(xl' + 2e - fl))  ==

>         (is_integer(xl' + e) && e == fl ? xl' + e - 1 :
>          is_integer(xl' + e) && e != fl ? xl' + e :
>         !is_integer(xl' + e) && e != fl ? floor(xl' + e)
>         !is_integer(xl' + e) && e == fl ? floor(xl' + e))  ==

>         (is_integer(xl' + e) && e == fl ? xl' + e - 1 : floor(xl'))

>     And the condition is equivalent to

>         (is_integer(xl' + e) && e == fl ? xl' + e - 1 : floor(xl')) <= i <
>         (is_integer(xr' + e) && e == fr ? xl' + e - 1 : floor(xr'))

>     But the old code computes

>         floor(xl') <= i < floor(xr'))

>     Thus when is_integer(xl' + e) && e == fl,
>     it wrongly shifts the rounded boundary in 1 pixel to the left.

>     EXPECTED DIFFERENCES :

>     Fix: Improving the decision whether the dropout prevention to be applied.

>     DETAILS :

>     1. The old code applied the dropout prevention
>     if gx_fill_params::adjust = 0.
>     It worked since the latter was set to 0 only for characters.

>     Now we intend to discontinue the fill adjustment with shadings,
>     so the old condition won't be applicable in further revisions.
>     Therefore we reserve the value -1 of gx_fill_params::adjust
>     especially for designating characters with a dropout prevention,
>     and percept it in the filling algorithm (We tried to use
>     new special flag for designeting characters,
>     but it requires an enhancement to the clist language.).

>     Now both the trapezoid and the scanline algorithm use same flattened path.

>     Differences in rasters appears due to 2 reasons :

>     1. An inprecise expressions used in the old algorithm in gx_curve_x_at_y :
>     the iteration of midpoint_fast accumulates a big rounding error.
>     The new algorithm have smaller error due to 3*log2(N) fraction bits
>     while the coordinate accumulation, where N is the number of flattened segments.

>     We believe that the the coord_near filter was implemented for
>     two purposes : (1) prevent the filling algorithm from
>     zero-height segments, and (2) speed up the filling with
>     reducing the number of vertices in the polygon.

>     Now the filling algorithms can handle zero length segments

>     DETAILS:

>     This problem surfaced when a previous fix 686815 was made.  That fix

>     Simplifying the filling algorithm, step B1.

>     DETAILS :

>     This starts a new sequence of patches to the filling algorithm.
>     It's goal is a further simplification.

>     We deetected that MERGE_COLLINEAR_SEGMENTS 1 section is an old optimization,
>     which speeds up in 1.3% and complicates the code in 30%.
>     Besides that, it causes inprecise results with the dropout prevention.
>     At last, the name "MERGE_COLLINEAR_SEGMENTS" doesn't reflect
>     its effect : actually it merges segments nearly parallwel to coordinate axis,
>     which may be unlimitedly long and have an unlimited angle.
>     Therefore we believe that this optimization is not well defined,
>     appears unuseful, and to be cancelled.

>     This patch is a preparation for removing the MERGE_COLLINEAR_SEGMENTS
>     section. We made this switch global and we bracketed more code sections,
>     which appear unuseful without MERGE_COLLINEAR_SEGMENTS.

>     This patch almost is a change to a disabled code.
>     But the change to gxfill.c ln 1238,1241 goes to the enabled code
>     and appears algorithmically equivalent :
>     with MERGE_COLLINEAR_SEGMENTS 1 this branch is equivalent to noop.

>     Create a new dynamic header 'gconfigd.h' for non-platform-specific defines. Variables like
>     GS_LIB_DEFAULT which were previously tacked onto the end of gconfig.h have been moved to the new
>     header. This change is necessary to pass the default path for the persistent cache from the
>     makefile.

>     DETAILS:

>     The persistent cache is implemented in the gp layer, but previously it was illegal to access
>     gconfig.h from code inside the graphics library, it the sense that the build would fail. This is
>     because of the crazy way operator definitions are collected in dev files before they are
>     consolidated in gconfig.h.

>     We don't want to use gconfigv.h because that header is platform-specific is generated by different
>     code on every platform. Therefore, while this isn't a real fix for gconfig.h circular inclusion
>     issue, a new header is reasonably motivated.

>     DETAILS :

>     When a path is is being stroked, it first converts to the stroke
>     outline, and pco_accurate is being applied. When the stroke outline
>     is being filled, pco_accurate was applied at second time with no
>     useful reason. When it fills a character, pco_accurate disturbs the

>     Fix : The PCL interpreter doesn't provide pattern streams.

>     DETAILS :

>     gx_pattern_cache_lookup falied when called by the PCL interpreter
>     because the PCL interpreter doesn't provide high level pattern streams.
>     Actially the compatibility of the graphics library to the PCL interpreter
>     was broken since gsptype1.c revision 1.16.

>     This patch introdices a new argument for the function gs_state_set_client.
>     Using the argument, a client tells to the graphics library
>     whether the client provides pattern streams. If not,
>     the graphics librery emulates the old behavior based
>     on raster parretns only.

>     The new flag gs_imager_state::have_pattern_streams stores the
>     compatibility mode. We would prefer it to be a member of the
>     graphics library instance, but the instance is not implemented yet.
>     Storing it to gs_imager_state may cause some undeserable effects,
>     especially when a device creates a temporary graphic state for
>     an internal use (the clist device is an example).
>     We assume that none of devices provides pattern streams,
>     and this assumption should be reasonable for current applications.

>     The mechanizm for generating patters streams is still
>     coded specifically to the PS interpreter in pattern_paint_prepare
>     in zpcolor.c . This solution to be considered as a temporary one.
>     We should refactor it into 2 parts : one specific for the PS interpreter,
>     and another one being common for all applications,
>     which should be a part of the graphics library.

>     Fix for "687252 subfiledecode errors on includes greater than the
>     size of a uint".  In spite of the bug name, the problem is not
>     related to the actual size of the subfile or to the size of a uint.
>     The actual problem is a missing required parameter:  EODCount.
>     However Adobe once again ignores the missing parameter and what is
>     specified in the PRLM-3rd.

>     DETAILS:

>     The given test file has a SubFileDecode filter without the required
>     EODCount parameter.

>     Ghostscript is rejecting the test file because the parameter is not

>       if ((code = dict_int_param(op, "EODCount", 0, max_int, -1, &count)) < 0)
>     	 return code;

>     This sets a default value of -1 for EODCount and then checks it
>     against the range 0 to max_int.  Thus when EODCount is not found
>     we get the rangecheck since -1 is outside the allowed range.

>     In spite of the fact that the EODCount is a required parameter,
>     Adobe Distiller 6.0, my CP1700PS printer, and CPSI 3010.105 print

>     Initial commit of the persistent cache implementation. This version supports only the *nix
>     platform and does not include any eviction logic. Also currently the cache directory and
>     empty 'gs_cache' index file must be created manually.

>     DETAILS:

>     Two new calls have been added to the gp layer: gp_cache_insert() and gp_cache_query(). These
>     take a byte buffer as a key under which another buffer can be stored or recalled. In addition to
>     the key, buffers are filed by 'type' which provides a separate namespace for each kind of
>     data. These types should be one of the GP_CACHE_TYPE_* defines in gp.h.

>     The query call takes a callback for allocating the buffer to be filled. Thus, all memory
>     management for the key and value buffers is handled by the client and the query returns
>     the data (if any) within a single call.

>     A pair of postscript test operators, .pcacheinsert and .pcachequery are provided in zmisc.c,
>     however they are disabled by default to prevent access to the cache by malicious postscript
>     programs. They operate only with the 'test' type, so a denial-of-service attack is the only
>     real risk; however we anticipate all access will be from C code. Compile with the DEBUG_CACHE
>     preprocessor symbol to enable these.

>     1.  We were not correctly recognizing that we can use a CalRGB color space

>     Fix : ..includecolorspace caused an abnormal recursion.

>     DETAILS :

>     1. With -dNOSUBSTDEVICECOLORS the procedure ..includecolorspace called
>     setcolorspace, which recursively called ..includecolorspace .
>     This recursion would be infinit unless an ocasional error
>     in a stopped context terminates it. We replace setcolorspace
>     with _setcolorspace_nosub to avoid the recursion.
>     This fixes the bug 687134 "-dNOSUBSTDEVICECOLORS causes text to disappear".

>     2. An optimization done with a new dictionary ..page_default_spaces,
>     which now keeps up to 3 global flags for Default* color spaces,
>     to reflect whether they were included into a current page.
>     It prevents redundant calls to _setcolorspace_nosub, .includecolorspace
>     from ..includecolorspace .

>     3. Moved .PurgeDict to gs_init.ps because now it is called from showpage, copypage .

>     4. Added a name argument to .includecolorspace and passed it through
>     a set of functions in the graphics library and pdfwrite.
>     Before that Default* color spaces were included into the PDF output
>     with wrong resource names.

>     5. Minor change : fixed a procedure header comment in gs_devcs.ps .

>     EXPECTED DIFFERENCES :

>     None, because the nightly regression doesn't test -dNOSUBSTDEVICECOLORS .

>     Fix for 686796 tiffg4 device and incorrect halftone frequency.
>     This eliminates a problem with not choosing the best halftone cell size
>     when more than one possible cell size has the exact angle requested.

>     DETAILS:

>     Previously the logic for determing the size of the halftone cells used
>     the product of the error in frequency times the error in the angle as
>     the metric for determing the best cell size.  For many common angles,
>     0, 45, 90, etc., this results in an angle error of zero.  This then
>     gave a value of zero for the metric no matter what the frequency error.
>     The result was that in many cases we ignored cell sizes that gave a
>     better frequency match.  The fix revies the metric to choose a cell
>     size which is closest (geometrically) to the ideal cell size.

>     Fix (font resource machinery) : Provide correct font names for graphics library.

>     DETAILS :

>     The old code passed names of substitutes rather than font names referred by a document.
>     This patch fixes that with adding a special ney entry /.Alias to the font dictionary.

>     Besides that, multiple problems are fixed in gs_fonts.ps,
>     some of them appeared before the repository was created.
>     Lising them here :

>     1. Several comments about stack layout in procedure headers were wrong
>        since the repository was created.
>        We repaired some of them, but possibly not all.

>     2. The old code assumed that SubstituteFont adds
>        a name to the stack rather than replaces it.
>        See comment inserted into .dofindfont .
>        The patch for the bug 637424 (Revision 1.24, Nov 21, 2002) broken the
>        old behavior and left multiple rudiments in code.
>        Now we restore the old functionality, and make SubstututeFont
>        to be compartible with CPSI, which replaces a name.

>     3. Now we define fonts for all aliases in the aliasing/substituting chain.
>        Not sure it is better than defining only the final one,
>        but the pre-repository code did so, and was
>        unintentionaly broken by multiple patches.

>     4. .stdsubstfont dropped some aliases with no strong reason.
>        Restoring the old behavior.

>     5. .tryloadfont damaged the stack balance. It was not visible due to (4).

>     6. We use a hack to provide the main functionality.
>        See comment in .aliasfont . A complete solution is too hard.

>     7. Inserted auxiliary comments about the stack layout.

>     Don't apply Type 1 hinting to charpath.
>     THIS IS AN INCOMPATIBLE CHANGE : charpath now creates a different outline than before.

>     DETAILS :

>     Adobe doesn't hint charpath.
>     Not sure why GS did.
>     This change makes GS to be closer to Adobe and
>     partially fixes the bug 687044 "strange elements with text".

>     Note that 'charpath fill' never was equal to 'show'. Neither the old hinter,
>     nor the new hinter, nor any combination of them in the pair ('charpath', 'show')
>     give same result. This happens because 'fill' uses the "center pixel inside" rule,
>     but 'show' uses a different one. With the new hinter 'show' performs
>     a spot topology analyzis during the rasterization. This rule doesn't belong
>     to the class of rules, which can be explained in terms "a part of pixel inside".

>     Thus, since "same" or "closer" result isn't possible,
>     the criterion for the choice must lie in another space.
>     I believe that the "Adobe compatibility" is the right one.

>     Besides that, Ghostscript PDF imperpreter emulates the text rendering modes 1,5,6
>     with 'charpath stroke', and with the hinted charpath the results look strange.

>     the UseCIEColor feature in PostScript.  This substitution is done inside
>     the PostScript code in lib/gs_devcs.ps.

>     Fix for 686948 Dotted lines messing in PDF.  Draw all line cap

>     drawn.

>     DETAILS:

>     This is a (minor) revision to a the previous fix from Jeong for
>     this problem.

>     For those people who do not remember, this problem involves a dashed
>     line with a zero line length for the imaged (pen down) part of the
>     dashed line.  Ghostscript currently calls this a degenerate situation
>     and does nothing except for round line caps.  Jeong had previously
>     proposed changing the test to any line cap except butt caps.  Jeong
>     removed this proposal after testing and finding that Adobe Acrobat
>     drew thin line segments even for butt line caps.

>     This proposal simply removes the test for line cap type completely.
>     It does still leaves a test for dot length = 0.

>     The routine already contains code for using adjacent line segments
>     to determine a 'direction' for zero length segments.

>     Testing with both butt and square line caps and with on axis and
>     diagonal lines produces results comparable to Adobe Acrobat.
>     (Acrobat is not consistent with segment widths for the butt joints.)

>     pdfwrite : Implementing a high level color handling.

>     DETAILS :

>     pdfwrite now passes colors identically except minor problems,
>     which should be fixed soon :

>     1. rectfill still converts colors.
>        This happens because gs_rectfill calls dev_proc(pdev,fill_rectangle),
>        which doesn't pass device color.
>        Therefore high level color is not available for pdfwrite.
>        This is an architectural problem which requires a hard decision.

>     2. Some documents (gs.anotherfailure.pdf is an example) generate
>        too many color space objects to the output PDF.
>        Requires an optimization.

>     THIS IS INCOMPATIBLE CHANGE for devices derived from gx_device_vector.
>     Now they must implement the new virtual function can_handle_hl_color.
>     A simplest impementation compatible to the old behavior is to return false.

>     DETAILS :

>     The new code uses the new functions gx_hld_save_color and

>     Cleans up the behavior of the .tempfile operator, primarily making it
>     consistent across all the platforms, ensuring that the TMPDIR and TEMP
>     environment variables are effective, the system temp directory is used
>     when these are not specified, and the permissions for tempfile
>     creation work as expected (allowed in the simple case, but closing off
>     potential vulnerabilities in other cases. Intended as a final fix for
>     bug #686922.

>     DETAILS:

>     1. The permissions behavior of .tempfile is changed so that simple
>     prefixes are always allowed, absolute pathname prefixes are checked
>     using the PermitFileWriting logic, and other cases are disallowed. In
>     particular, it is no longer possible to specify temp prefixes relative
>     to the current directory, or as subdirectories of the standard temp
>     directory. Both such cases are potential security holes, and are
>     probably not useful in any real application.

>     2. The meaning of gp_open_scratch_file() is made more consistent
>     across the platforms. In particular, it is now the clear
>     responsibility of this function to add the appropriate temp
>     directory. As such, gp_gettmpdir() is no longer exported in the public
>     gp.h interface (gpmisc.h is intended only for the convenience of gp_
>     implementations).

>     3. On VMS, gp_open_scratch_file() didn't previously add the
>     temporary directory pathname. Now it does.

>     4. On Windows, gp_open_scratch_file()'s behavior was somewhat
>     inconsistent, calling GetTempPath() only when the length of the TMPDIR
>     or TEMP environment variables overflowed the buffer provided. It
>     now additionally uses GetTempPath() in the cases where these
>     environment variables are not set.

>     5. Since gp_open_scratch_file() now takes responsibility for
>     determining the temporary directory, ztempfile() no longer attempts
>     to do this.

>     Initial check in of the native font enumeration mechanism with an implementation for MacOS. The
>     code is currently disabled pending resolution of bugs regarding some font files.

>     DETAILS:

>     This adds a trio of gp_enumerate_fonts calls which implement an interator for querying the native
>     operating system for font files. This is essentially required to make use of the support for
>     reading resource-based font collection files on MacOS since there is no convenient way to
>     construct a Fontmap by hand. Thus our initial implementation focusses there and only stubs are
>     provided on other platforms. However, it would generally be a useful feature on any system that
>     provides such services.

>     An iterator object is created with gp_enumerate_fonts_init() and released with
>     gp_enumerate_fonts_free(). Between these calls, each font is returned by a successive
>     call to gp_enumerate_fonts_next() as a pair of C strings giving the access path and reported font
>     name.

>     On MacOS these are implemented using the FMFontIterator API from Carbon. Unfortunately, while this
>     returns font names and files, it does not provide details about the resource internals so we must
>     open the file and extract the resource id corresponding to the font itself. It also is not always
>     possible to obtain the correct postscript name from the OS call.

>     Connection is made to postscript through the .getnativefonts operator, implemented in zfontenum.c.
>     I handles the interation and places the results on the stack as an array of two element arrays,
>     each representing the name and path as postscript strings. New code in gs_fonts.ps calls this and
>     adds the entries to the fontmap after first calling .findfontname on each path to verify
>     accessibility and in case the reported font name is unreliable. This is implemented as the
>     .buildnativefontmap procedure, which is called by the font location logic if a requested font
>     is not found in the Fontmap.

>     Caveats: This can be a very expensive operation, so like the FONTPATH directory scanning it should
>     probably only happen once in a given session, instead of every time a font isn't found. The macos
>     implementation could also be considerably streamlined.

>     Permit explicit specification of /GDBytes equal to 0 for incrementally
>     downloadable CIDFonts.
>     Fixes bug 686890 from customer 131.

>     DETAILS:
>     Incrementally downloadable CIDFont has GlyphDirectory key. According to
>     PLRM3 p. 376 "The binary data section of a CIDFont with a GlyphDirectory entry
>     does not need a charstring offset table or charstrings; if present, they will
>     be ignored". PLRM3 says nothing about GDBytes entry but it seems logical that
>     the entry is no longer needed when the structure it describes is ignored.

>     Old code used 0 as a default GDBytes value but required explicit specification
>     to be > 0. New code permits explicit 0 value because "Acrobat PDFMaker 5.0 for
>     Word" generates it.

>     Fix (pdfwrite) : Convert Type 0 fonts with multiple CID font descendents into
>     Type 0 fonts with single CID font descendents (the part 3).

>     DETAILS :

>     At last we got a non-degenerate test for multiple CID font descendents
>     and could debug this stuff with a real document.

>     This patch mixes several changes :

>     - In some cases CIDFontType 2 fonts wrongly computed glyph indices ignoring GlyphDirectory.
>       The new function z11_glyph_info works for it.

>     - The text decomposition in gdevpdtc.c mixed font indices of various font descendents.

>     - font->procs.get_glyph_info sometimes received glyph indices
>       instead glyph names or CIDs. This happened with subglyphs of a CIDFontType 2 glyph.
>       This patch improves the semantics of gs_glyph with distinguishing
>       CIDs and GIDs with a new tag in the 2nd high order bit.
>       The new macro GS_MAX_GLYPH_INDEX and related stuff
>       works for it.

>     - gdevpdtd.c tried to compute CID font features using glyph names,
>       which don't exist in this case. Replaced with CIDs.

>     - In gdevtrac.c a wrong glyph space was specified enumerating glyphs
>       (a minor change, since gdevtrac.c is almost an example).

>     - Fixed a compiler warning in gdevdevn.c .

>     Working on this patch, we can see rudiments
>     in pdfwrite code, which are inherited from pre-8.00 code
>     (before stable font copies are implemented), which to be fixed someday :

>     - subset_glyphs arguments in gdevpsft.c looks always NULL
>       and probably to be removed;

>     - COPY_GLYPH_BY_INDEX is now obsolete and to be removed;

>     - glyph enumeration procedures (*enumerate_glyph*) sometimes retrieve
>       a wrong tag in gs_glyph values. The new macro GS_GLYPH_TAG works against it,
>       rather an improvement to enumeration procedures would be useful.

>     The patch is debugged with korea.ps from the bug #686894.
>     After this change the embedded composite font with 2 CIDFontType 2
>     descendents is correctly decomposed into 2 Type 0 fonts with
>     single descendents (the old (gs8.10) code converts it into a Type 3
>     with outlines). The generated PDF satisfies the PDF specification
>     and Ghostscript can handle it. Meanwhile Acrobat Reader 4,5,6
>     fails with it. It appears an old known problem :
>     if a Type 42 font and a CIDFontType 2 with a non-standard CMap
>     appear in same PDF document, Acrobat Reader fails.
>     We believe it's a bug in Acrobat reader, because if we
>     modify the document with removing portions of text so that
>     only one of the 2 fonts is really used, Acrobat Reader renders it fine.
>     It fails only when both things are really used for rendering.
>     A workaround for this problem to do separately.

>     DETAILS:

>     The previous testing had on the rebuild facility had verified that

>     of the files in the regression test suite has found three cases of
>     the output images not matching between the normal PDF processing

>     1.  Many real life PDF files contain garbage after the final %%EOF

>     some time.  I found a test case (adesso6.pdf) in which the repair
>     logic was finding what it considered a valid object in this garbage.
>     The revisions determine the location of the last %%EOF and form a
>     count of the data left in the file after the %%EOF.  This count is
>     used to exclude this data from the object scanning and the trailer
>     location scanning.

>     2.  A test case was found in which two objects were found to have
>     the same object number and revision number.  By my reading of the
>     PDF spec, the newer object should have a higher revision number.
>     However the object scanner was changed to accept the last such
>     object as the desired one.  Most PDF editors (at least Adobe) put
>     updated objects at the end of the file.

>     3.  A test case was found in which a Linearized PDF file had been
>     edited and a new xref list and trailer dictionary were placed at
>     the end of the file.  The heuristic for finding the trailer dictionary
>     was changed to check the specified location of the 'first' xref list.
>     If this location is in the first half of the file, then the start of
>     the file is searched for the first trailer.  Otherwise the end of the
>     file is searched for the last trailer.

>     With these three changes, all of the PDF files in the regression
>     test suite produce matching results using either the normal PDF
>     processing or the rebuild procedures.

>     The TrueType font loading was quite a bit slower than it should be. This
>     optimized font loader is up to ten times faster. Fixes bug #686851.

>     DETAILS:

>     Analysis of the time spent during TT font loading led to two problem areas.

>     The first was that the cmap array was built inefficiently when their was
>     a large glyph range, that had large holes was built with a loop that
>     called a PostScript function 'putglyph' to fill unused areas with .notdef
>     (glyph ID 0). The revision pre-fills the 'glyphs' array with .notdef from
>     a static array pre-filled with 1024 zeroes.

>     The second problem was the code that built the encoding using the 'post'
>     table. This code had a 'repeat' loop to find the name from the start of
>     the glyphNames section of the 'post' table for each named glyph in the
>     encoding. By creating a temporary cross reference, only one pass through

>     Correct the implementation of the new file_name_combine operators for MacOS.

>     Details:

>     The parent directory reference prefix is '::' rather than ':'. Also, a path
>     that begins with the ':' directory separator is a relative path from the
>     current working directory.

>     The more substantive change is in the implementation on gp_check_root(), intended
>     to return the 'root' prefix of a path, if any. The previous implementation returned
>     the location of the first patch separator, causing initialization to fail when
>     attempting to determine if GenericResourceDir ends in a directory separator in
>     gs_res.c.

>     Absolute paths are not a well defined concept on Classic MacOS. In that case we just
>     return 0, as if no path were ever absolute. This likely causes other problems not
>     addressed here. In the Carbon build, we make use of the FSGetVolumeInfo() call
>     to enumerate all mounted volumes, attempting to match each one. This call returns a
>     16-bit char unicode name for each volume which we make no attempt to convert to
>     whatever 8-bit encoding ghostscript might receive the path in orginally; however
>     we do match the lower 8 bits for the first 256 characters, which works well enough
>     for English volume names.

>     Note that this patch only provides support for MacOS-style paths with ':' as a
>     separator. The Metrowerks Standard Library also accepts unix-style paths and
>     on MacOS X users will expect to be able to use them. Support will need to be
>     extended to include this.

>     This is a set of routines for attempting to recover PDF files which
>     have been mangled by EOL conversions.  This is a facility which Adobe
>     Acrobat has and thus we need to duplicate.

>     DETAILS:

>     THE PROBLEM:

>     The basic problem is that PDF files contain 'xref tables' which are
>     really object location indexes which contain the absolute position of
>     objects in a file.  If a file is changed by converting the type of
>     EOLs then the file size is changed and the xref data is no longer
>     valid.  In many cases, Acrobat can rebuild these files.  It is not
>     always possible to always rebuild files.  If the files contain binary
>     data which contains line feed or new line characters then the binary
>     data may be mangled and cannot be rebuilt.  We need to be able to
>     duplicate Acrobat's ability for rebuilding files.  (Note:  In theory
>     one can get more and more sophisticated about rebuilding files.  The
>     techniques used in this code are quite simple but effective.)

>     THE BASIC SOLUTION:

>     The solution to this problem consists of several pieces.  The first piece
>     was to modify the pdf interpreter's internal representation of the xref
>     data.  The xref data is stored into two larrays.  The larray Generations
>     contains the object's generation number.  This was not changed.  The
>     larray Objects contained the location of the xref entry in the file.
>     This was set initially by the readxref routine.  Since the xref entry
>     data is not valid (for mangled files) this was not useful.  Objects
>     was changed to contain the actual location of the object in the file.
>     This actually eliminates one step in the process.  Previously when an
>     object was referenced, the location of the xref entry in the file was
>     obtained from Objects and then the xref entry was read to determine
>     the actual location of the desired object.

>     The second part of the process was to put .internal_stopped trapping
>     around the two usages of readxref to catch any failures of that routine.
>     An error message is printed and we then try to rebuild the locations
>     of the objects and find the proper trailer dictionary.

>     The third part of the process is to locate the objects in the file.
>     This is done by a simple scan of the file looking for lines beginning
>     with x y obj where x is a object number and y is object generation
>     number and obj is the text 'obj'.  In theory this simple strategy can
>     be confused by binary data but with over 156 files tested, no problems
>     were found.

>     The fourth part of the process is to locate the appropriate 'trailer'
>     dictionary.  There is a trailer dictionary with each xref list.  In
>     theory there can be many trailer dictionaries in a file.  The only
>     desired trailer dictionary is the one associated with the 'first'
>     xref list.  Unfortunately since we cannot count on the location
>     information in a mangled file, following the xref links is problematic.
>     The solution used is simple.  For Linearized pdf files, we find the
>     first (at the front of the file) trailer dictionary otherwise we use
>     the last trailer dictionary in the file.  This simple method works
>     for the 151 known good files (see testing below) and all five known
>     bad files.

>     Included are diffs for the changes and the new file lib/pdf_rbld.ps.
>     The only change in the src directory was the addition of pdf_rbld.ps
>     to the int.mak file.

>     TESTING:

>     There have been two sets of test run on this code.  The first set
>     consists of running 151 pdf files from our regression test suite.
>     These files are not mangled.  However by disabling the normal readxref
>     routine, the new code was exercised.  All 151 pdf files were displayed
>     correctly.

>     The second set of tests consists of actual problem files.  I was able
>     to locate five files that we have been sent that have been mangled.

>     file name		Ghostscript	Acrobat 5.0.5
>     1003.pdf		   okay		   okay
>     cm_test.pdf		   okay		   okay
>     precon.pdf		   okay	  	   fail
>     ServletReport.pdf	   fail	       	   fail
>     dauben.pdf		   fail		   fail

>     As expected, not all files can be recovered.  I was pleased that,
>     for this small sample, we did better than Acrobat.

>     Log Message:

>     This is the fix for 686798 /typecheck in --setcolorspace-- with
>     -sDEVICE=x11cmyk. This fix increases the stack checking while sampling
>     tint transform functions. It also makes the error handling more robust
>     for invalid tint transforms.

>     DETAILS:

>     It is sad to say but this is a bug that we have seen before, several
>     times.  Ray and I fixed this problem at the last code fest in September.
>     However that fix did not make its way into CVS.

>     The cause of this problem is that certain proc sets from Adobe violate
>     the PLRM.  In the test file, the proc set is from Adobe Photoshop
>     Version 5.5.  The proce set contains tint transform functions which
>     violate the specification in two different ways.  In one case, the tint
>     transform function changes stack values outside of the given color value.
>     This is used as a test to see if the interpreter supports the given
>     duotone color space.  If so then the proc set creates a color space with
>     a tint transform which is unbalanced in its stack usage.  This could
>     cause a stack overflow/underflow during sampling of the tint transform.
>     Adobe apparently assumes that this tint transform is never executed
>     since the function starts with the name /NeverReached.

>     The fix involves checking the stack depth after each execution of the
>     tint transform function and verifying that it matches the correct
>     position given the number of function inputs and outputs.  If so then
>     the stack is returned to its original position and the sampling is
>     aborted.  Changes in lib/gs_sepr.ps make the tint transform sampling
>     logic more robust in case the tint transform modifies the top of the
>     stack.  (This occurs in this case since the tint transform is actually
>     popping extra items off of the stack.)  We also create a dummy tint
>     transform function if sampling fails.  The later was done to prevent
>     the /typecheck error and give pdfwrite something with which to work.

>     A preparation for non-convert PatternType 1 to rasters with pdfwrite.

>     DETAILS:

>     The patch defines a new device virtual function pattern_manage,
>     and a default implementation for it. The purpose is to inform
>     the device about pattern accumulation and to bypass the installation of
>     gx_device_pattern_accum when the device can handle the pattern command stream.

>     The new code is temporary disabled with PATTERN_STREAM_ACCUMULATION 0
>     macro defined in gx.h . When it is 0, the new device virtual
>     function is provided but never called. The behavior should not change.

>     The rest of this log message describes PATTERN_STREAM_ACCUMULATION 1.
>     In this mode pdfwrite doesn't convert PatternType 1 to rasters.
>     It creates good PDFs at least with 012-09.ps and 269-01.ps
>     (these are very complicated cases with patterns inside charprocs and patterns),
>     but there are problems when rasterizing the resulting PDFs with GS.
>     (A new bug 686834 issued for tracking this problem).

>     When a pattern stream is handled by the device,
>     we can't create a proper content of gx_color_tile.
>     However we need a correct content if the pattern is used
>     for rasterization of an object which the device can't handle
>     at the high level. An example is pdf14 device during a PDF re-distillation,
>     which handles transparency. Another example is
>     a conversion of composite fonts, which have multiple CID descendents -
>     pdfwrite still converts such fonts to raster fonts.

>     Since a proper contents may be needed for gx_device_color,
>     we define a new flag gx_color_tile::is_dummy, and account it in
>     gx_pattern_cache_lookup. Thus, if the current device is cache device
>     installed for the font conversion, the tiles with is_dummy == true
>     are being be dismissed. Vice versa, tiles with is_dummy == false are
>     being dismissed when current device is pdfwrite.

>     We do not move parts of zpcolor.c code to gx_default_pattern_manage,
>     because we don't see a proper place for it to be compatible to
>     the FEATURE_DEVS configurability. Instead that, we implement
>     a branching inside gsptype1.c and zpcolor.c . If more branches will
>     be necessary in future, this to be improved with moving code
>     fragments to specific implementations of pattern_manage,
>     together with improving the FEATURE_DEVS modularity.

>     They to be removed after beta-testing.

>     Change to makefiles provide extended default values for
>     file search paths, which are platform dependent.

>     For convenience, here we summarize all related issues,
>     which were mentioned in previous patches :

>     1. The search method with multiple resource directories
>        appears not fully conforming to PLRM. We cannot ever call
>        ResourceFileName while executing findresource
>        or resourcestatus, because per PLRM it always
>        returns a single path. Therefore we implement
>        an extended search method in findresource,
>        resourcestatus and resourceforall, which first calls
>        ResourceFileName and checks whether the returned path
>        points to an existing file. If yes, the file is used,
>        othervise we search all directories specified in
>        LIB_PATH. With a single resource directory
>        it appears equivalent to Adobe.
>        THIS IS INCOMPATIBLE CHANGE.

>     2. ResourceFileName may be used for obtaining a path
>        where a resource file to be installed. In this case
>        Ghostscript to be invoked with -sGenericResourceDir=path,
>        specifying an absolute path. The default value for
>        GenericResourceDir is a relative path. Therefore
>        a default invocation with a Postscript installer
>        will install resources into gs/Resource.
>        THIS IS INCOMPATIBLE CHANGE.

>     3. We do not distinguish lib and Resource directories.
>        There is no file name conflicts because
>        lib does not contain subdirectories, but Resource
>        always store files in subdirectories.

>     4. We implement a new flag in gs_context_state,
>        which informs lib_file_open whether it is invoked
>        with a file specified in a command line argument.
>        Doing so because command line argument files
>        don't need to check permissions, and they
>        are executed with a special PS operator .runfile .
>        We cannot use a .runfile argument for passing this
>        information, because it would be a security hole
>        due to .runfile is available for documents
>        and cannot be hidden.

>     5. We still have a security hole while loading
>        resources from gs_init.ps .
>        Both the old and the new code load some resources
>        (such as CIDInit ProcSet) before entering
>        the SAFER mode. Therefore it is a way for
>        Postscript viruses to migrate.
>        To be fixed later.

>     6. Default values for GenericResourceDir and FontResourceDir
>        are platform dependent.
>        (The old code always use Unix notation - a bug).

>     7. Default value for GenericResourcePathSep is platform dependent.
>        The value is used before non-directory items only.
>        (The old code always use Unix notation - a bug).
>        (The old code used the value before directory items - a bug on OpenVMS).

>     8. If a path starts with a number of parent references,
>        a template with same number of parent references
>        must be added to permission list to allow the access in SAFER mode.
>        The template (*) allows access to any file.
>        THIS IS INCOMPATIBLE CHANGE, because
>        the old code ever rejects parent directories.

>     9. GenericResourceDir and FontResourceDir are not being added
>        to permission list while .locksafe. Instead that,
>        we generate (*/*) templates with all LIBPATH items.
>        THIS IS INCOMPATIBLE CHANGE, but for non-exotic cases
>        (such as "(./Resource/CMap/H) .libfile" in a document)
>        it should not be visible.

>     A. Scratch files with a non-absolute prefix always open
>        in a scratch directory. The old code can open them
>        in current and parent directories if an user modified
>        a default prefix in C code.
>        THIS IS INCOMPATIBLE CHANGE for users who had modified
>        a scratch file prefix in C code.
>        Permission for scratch directory is not checked
>        as well as in old code.

>     B. The operator .filenamedirseparator is removed,
>        because it cannot work properly on OpenVMS.
>        On OpenVMS it needs both prefix and trailer to
>        determine a correct separator.
>        We removed it because the new logics never needs it.

>     C. The operator .pathstring_not_bare is removed,
>        because .file_name_combine performs it's job better.

>     D. The functions gp_pathstring_not_bare, gp_file_name_references_parent,
>        char *gp_file_name_concat_string are removed.

>     E. New operators added to maintain the new logics :

>           .file_name_combine  true
>           .file_name_combine   false

>           Combine a file name with a prefix.
>           The first argument is a prefix, the second is a file name.
>           Internal syntax of arguments and result is platform dependent.
>           The combination is being reduced to a shortest equivalent,
>           but if it starts with cwd reference, the starting
>           cwd reference persists.

>           If the  argument is true, it considered to use the
>           "no sibling" mode. It prevents reduction of
>           (x/../y) to (y) for any x != y. With false such reduction
>           is allowed. The  argument appears a rudinemt from
>           a dead branch. The new code always sets it to false.

>           On success, the result is a combined, reduced path and false.
>           On failure, the argument strings left on operand stack,
>           followed with false.

>        - .file_name_separator

>     Fix (pdfwrite) : Provide a complete monitoring of the viewer's graphic state
>     while generating a PDF output. The old code misses the synchronization
>     of the viewer's graphic state with its internal copy when generating
>     a 'grestore' command to undo a clipping.
>     Bug 686763 "pdfwrite is not correctly handling OPM distiller parameter".

>     DETAILS :

>     This change affects all vector devices, but it should be equivalent
>     for all them except pdfwrite, and except for the pointer lifetime bug
>     explained below.

>     Here is an example when the desynchronization appears :

>       f1 settransfer
>       0 setcolor
>       path1 fill
>       f2 settransfer
>       1 setcolor
>       path2 fill
>       gsave
>       path3 clip
>       path4 fill
>       grestore
>       path5 fill

>     After 'grestore' it uses f1 instead f2.

>     The old code does not remember the viewer's graphic state,
>     which was immediately before 'gsave', and resets the internal copy of
>     the graphic state to default values when it generates 'grestore'.
>     This logic is fully wrong : if after 'grestore' a parameter is equal
>     to the default value, pdfwrite does not generate a set command for this parameter,
>     but the viewer uses the value which was set before 'grestore',
>     which can differ from the default one.

>     Moreover, gdevvec copies the device color from local memory
>     to global memory, and doesn't ask garbager to process pointers in
>     the copy. When the device color contains pointers
>     to patterns or so, the live time of the copy appears bigger
>     than the live time of the pointed structure. The old code only
>     compares the pointed addresses without accessing the pointed data,
>     so that a crash can't happen. But if garbager moves another color
>     to same address, the comparison answers "equal" when actually colors
>     are not equal, and the generated PDF appears wrong.

>     To exclude the pointer lifetime problem, the patch uses the 'save_dc' method
>     instead the 'equal' method for colors. But the implementation
>     of save_dc was dummy for patterns. To complete it, gs_id is
>     inserted into gs_pattern_instance_s, and more variants added to
>     gx_device_color_saved_s. The clist device appears tolerant
>     to this change.

>     Note that macros color_unset, color_set_null, color_is_null,
>     gx_dc_is_null are now applied to gx_device_color_saved.

>     For complete monitoring the viewer's graphic state,
>     we implement a 2-elements stack 'vgstack' in gx_device_pdf_s,
>     save the viewer's graphic state in it when generating 'q' commands,
>     and restore from there when generating 'Q'. If a 'gs' parameter
>     needs to change, we move to 'PDF_IN_STREAM' context, because
>     we must not insert 'gs' into a text context. New functions
>     pdf_try_prepare_stroke and pdf_try_prepare_fill provide
>     the "try" logics for this.

>     If a 'gs' parameter changes with changing a clipping,
>     first we need to undo the old clipping with 'Q',
>     and then generate new 'gs' parameters relatively to the
>     restored graphic state. The new function pdf_unclip
>     works for this.

>     With this patch the length of generated PDF appears longer
>     for some tests. The most important ones are :

>     acrobat.pdf        Lengths differ in 6141.
>     adesso8.pdf        Lengths differ in -8316.
>     HeiseiMinStd.pdf   Lengths differ in 4000.
>     narrow_font.pdf    Lengths differ in 6141.
>     RealCities.pdf     Lengths differ in 12370.
>     RodinCIDEmbed.pdf  Lengths differ in 101698.

>     It happens because pdfwrite doesn't remember 'gs' dictionaries,
>     and therefore redundant copies can appear.
>     This problem to be fixed separately.

>     Expecting a progression : 093-01.ps (was a wrong stroke widths with a PaintType 2 font).

>     Expecting a regression : with this patch, re-distilled
>         Testform.v1.0.2.pdf paints good with Adobe, but wrongly with GS.
>                              Maybe a bug in GS PDF interpreter.

>     Ghostscript implements an extended semantics.

>     Finding a resource file while executing findresource or resourcestatus,
>     Ghostscript does not call ResourceFileName. Instead that, it searches directories
>     with an extended method explained in How Ghostscript finds files.

>     ResourceFileName may be called from a Postscript program such as a resource installer.
>     The default implementation for ResourceFileName first checks whether
>     GenericResourceDir specifies an absolute path. If so, ResourceFileName uses its value

>     Initial commit for the new SAFER logics.

>     DETAILS:

>     This patch should not change any behavior unless
>     NEW_COMBINE_PATH is changed to 1. With 0 a minor meanful
>     change is the replacing .pathstring_not_bare with .file_name_combine
>     in gs_fapi.ps (which fixes a bug in FAPI support,
>     and doesn't affect builds with no FAPI).

>     The change is compatible unless NEW_COMBINE_PATH is 1.
>     Incompatibility issues with 1 are explained below.

>     With NEW_COMBINE_PATH 1 the patch defines a new logic for
>     .libfile, SAFER, and related things :

>     1. Default values for GenericResourceDir and FontResourceDir
>        are platform dependent.
>        (The old code always use Unix notation - a bug).

>     2. Default value for GenericResourcePathSep is platform dependent.
>        The value is used before non-directory items only.
>        (The old code always use Unix notation - a bug).
>        (The old code used the value before directory items - a bug on OpenVMS).

>     3. PLRM specifies GenericResourceDir to be a single absolute path name.
>        But Ghostscript's tradition is to load library files
>        form a list of directories. Since we want to propagate
>        this tradition to resource files, we get a conflict.
>        To resolve the conflict, we allow GenericResourceDir
>        to be a relative path, which is being concatenated with
>        LIBPATH items. Thus we provide an extension of Postscript.

>     4. When a LIBPATH item is being concatenated with GenericResourceDir,
>        an abnormal behavior appears when GenericResourceDir references parent.
>        Exactly, concatenating the (.) item of LIBPATH with
>        the default GenericResourceDir, which is (../Resource/),
>        we get (../Resource/), i.e. it searches in a directory,
>        which users don't expect to. We work around the abnormal
>        behavior with skipping such paths while executing .libfile .

>        More precisely, the .libpath algorithm is :

>        For each LIBPATH item :
>           - combine it with the argument string;
>           - if the (reduced) combination refers the parent, skip it;
>           - otherwise try to open the path. If succeeded, exit with it.
>        If no success, fail with undefinedfilename or invalidfileaccess.

>        Here and below we used Unix notation just for simplifying
>        the log message. All statements to be generalized for any platform,
>        and they are true for any supported platform.

>     5. A consequence of our workaround for (4) is a new constraint to .libfile :

>        Let x is a cwd.
>        Let x/../y exists. Lets mark it as y1.
>        Let LIBPATH contains cwd and a directory z, which is not cwd.
>        Let z/../y exists. Lets mark it as y2.
>        Consequently y1 != y2.
>        Executing

>           (../y/f) .libpath

>        searches y2/f, but does not search y1/f .
>        The old code searched both in non-safer mode.
>        THIS IS INCOMPATIBLE CHANGE.

>     6. A better workaround for (4) would be an implementation
>        of RESPATH, which by default generates from LIBPATH
>        with replacing (../Resource/) with (./Resource/).
>        This requires to maintain a new directory lists.
>        .libfile should get an additional argument,
>        which specifies a search list - LIBPATH, RESPATH or FONTPATH.
>        We do not make this improvement now,
>        but will add it to Issues.htm .

>     7. If a path starts with a number of parent references,
>        a template with same number of parent references
>        must be added to permission list to allow the access.
>        The template (*) allows access to any file.
>        THIS IS INCOMPATIBLE CHANGE, because
>        the old code ever rejects parents.

>     8. GenericResourceDir and FontResourceDir are not being added
>        to permission list while .locksafe. Instead that,
>        we combine them with all LIBPATH items,
>        and add the combinations to the permission list
>        unless it references parent.
>        THIS IS INCOMPATIBLE CHANGE, but for non-exotic cases
>        (such as "(../Resource/CMap/H) .libfile" in a document)
>        it should be equivalent to the old behavior.

>     9. Scratch files with a non-absolute prefix always open
>        in a scratch directory. The old code can open them
>        in current and parent directories if an user modified
>        a default prefix in C code.
>        THIS IS INCOMPATIBLE CHANGE for users who had modified
>        a scratch file prefix in C code.
>        Permission for scratch directory is not checked
>        as well as in old code.

>     A. The operator .filenamedirseparator is removed,
>        because it cannot work properly on OpenVMS.
>        On OpenVMS it needs both prefix and trailer to
>        determine a correct separator.
>        We removed it because the new logics never needs it.

>     B. The operator .pathstring_not_bare is removed,

>     C. The functions gp_pathstring_not_bare, gp_file_name_references_parent,
>        char *gp_file_name_concat_string are not longer in use.

>     D. New operators added to maintain the new logics :

>          .file_name_combine

>           Combine a file name with a prefix.
>           The first argument is a prefix, the second is a file name.
>           Internal syntax of arguments and result is platform dependent.
>           The combination is being reduced to a shortest equivalent,
>           but if it starts with cwd reference, the starting
>           cwd reference persists.

>        - .file_name_separator

>           Returns a readonly string, which represents a separator
>           which is used in file names between directory item and file item.
>           Used for making the default value of GenericResourcePathSep.

>        - .file_name_directory_separator

>           which is used in file names between two directory items.
>           Used for making the default value of GenericResourceDir.

>        - .file_name_parent

>           Returns a readonly string, which represents a parent reference.

>     This is initial commit for implementing static resources.

>     DETAILS :

>     1. Adding a new iodevice %static% with the new file ziodevst.c .
>     It is used for opening files placed in static data segment.
>     They need to be accessed as PS files due to multiple reasons,
>     including the implementation of gs_ciddc.ps and for PS procedure
>     ResourceFileName defined in PLRM.

>     2. Implementing a queue for delayed invocation
>     of initialization functions at end of gs_init.
>     This feature is necessary due to customized
>     builds of Ghostscript : some 'dev' depend each
>     on other and some functions are needed to execute
>     after all devs are preset. Currently it is only used
>     for obtaining the Unicode Decoding resource,
>     but later it will be used for perfectly consistent
>     processing of font and CID font map files,
>     both with FAPI and without it.

>     3. gs_resmp.ps slightly changed for handling
>     resource maps which are not defined as files.

>     4. The new file gs_resst.ps implements a procset
>     for handling static resource files. Both gs_resst.ps and
>     gs_ciddc.ps use the %static% iodevice.

>     5. The new file gs_resst.ps creates a map of resource files
>     placed in static segment. Later it would be nice
>     to generate it during GS installation. With the defined
>     resource set gs_init.obj grows up to 1.5Meg,
>     but both MSVC and gcc/Cygwin could handle it.

>     Currently all resources in gs_stres.ps are COMMENTED OUT
>     to prevent problems building Ghostscript with COMILE_INITS=1
>     on Mac and VMS. To uncomment them, replace '%-' with empty string.

>     This patch was locally tested with entire comparefiles
>     with COMPILE_INITS=0. It should not cause regressions.
>     Also it was slightly tested with COMPILE_INITS=1 :
>     the static resources work fine.

>     The patch assumes that during a GS build resource files
>     are placed in gs/Resource/ . It uses 1 Decoding and
>     a dozen of CMaps, which are necessary for the CID font emulation
>     and for FAPI to work. You need to uncomment them
>     in gs_stres.ps .

>     When GS is invoked, resources are being loaded from both
>     the static segment and from the OLD(!!!!!) default path.
>     In other words, the resource machinery works fine,
>     but the default resource path is not fixed yet.
>     I intend to fix it in the next day or two.

>     The patch depends on

>     Fix : Improving the CIDFontType 2 font copying.

>     DETAILS :

>     I believe that the code about copying CIDFontType 2 glyphs
>     is overcomplicated with mixing CIDs and GIDs, and needs to be
>     cleaned up. The old code had an obvious inconsistency :
>     it allocated a smaller array for glyph indices than written,
>     causing a heap damage. This patch simply makes the code to be
>     self-consistent. I can't say that I completely
>     understand whether CIDs/GIDs passed correctly or not.
>     Now it is working, but the correctness was not proved,
>     and Acrobat Reader doesn't show the glyph with /CIDTTEMUL
>     (see below).

>     The problem was detected with COMPILE_INITS=1 with emulating
>     a CID wont with mshei.ttf . The following program had crashed
>     with pdfwrite :

>     /CIDTTEMUL /CIDFont findresource
>     100 scalefont setfont
>     100 100 moveto glyph glyphshow
>     showpage

>     with the cidfmap file like this :

>     /ShinGo-Bold << /FileType /TrueType /Path (f:/WIN2000/Fonts/batang.ttf) /SubfontID 0 /CSI [(Japan1) 2] >> ;
>     /CIDTTEMUL << /FileType /TrueType /Path (f:/WIN2000/Fonts/mshei.ttf) /SubfontID 0 /CSI [(Japan1) 2] >> ;

>     The effect is indeterministic.
>     When I build GS with regenerate gs_init.c,

>        The function was factored out from an old code.

>     2. Provided a default metrics for CID fonts for WMode 1.

>     The new type 1 hinter (with NEW_TYPE1_HINTER = 1 in gx.h)
>     puts more 11K of data to C stack. Perhaps due to a recursion
>     in bbox_draw 2 instances of the hinter were placed in C stack
>     simultaneously, causing C stack overflow with gswin32c.exe on

>     Perhaps the recursion is not necessary.
>     Reorganizing the sequence of calls to avoid the recursion.
>     New argument 'exec_cont' was added to several
>     functions for transferring the call request to clients.
>     Corresponding comments are added in code.

>     Also z1_glyph_info prototype was added in ichar1.h .
>     It was missed a long time ago, Cygwin/gcc warned.

>     A further improvement may be done with factoring out

>     of the old hinter. Perhaps it discovered a defect

>     This is a porting from HINTER branch.

>     The old hinter cannot handle overlapping hints,
>     but real fonts do use them.

>     The handling of overlapped hints cannot be done within

>     When adding a missing showpage to an EPS file,
>     don't bind showpage to allow user to override it.

>     DETAILS:
>     The EPS encapsulation code in ghostscript adds a showpage
>     if one is not present, so that displaying, printing and
>     converting all behave the same.  Some users are feeding
>     multiple EPS files to ghostscript, intending to print them
>     on a single page.  The current code will print each EPS file
>     on a single page.  For example following code would print
>     three pages:
>       save
>        /showpage {} def
>        save (file1.eps) run restore
>        save (file2.eps) run restore
>       restore
>       showpage
>     With this fix, it will print a single page.

>     Other ways to avoid this problem are to use -dNOEPS,
>     or (file.eps) (r) file cvx exec

>     The attached code release fixes a variety of memory handling problems
>     discovered by Dan's test with the memory validation enabled.

>       1. Most of the problems with the FTS were accounted for by a relatively
>          harmless dangling pointer problem for paths. In order to support the
>          charpath operator, paths are normally constructed in stable memory
>          (not subject to save/restore). However, clipping paths were
>          constructed in normal memory. If the clippath operator was used to
>          make the clipping path the current path, the top-level
>          gx_path_segments would be in stable memory, while the rest of the
>          path would be in normal memory. A restore operation could then
>          leave dangling pointers.

>          This is not normally a problem, because the grestore operation
>          associated with the restore would clear the gx_path_segments
>          structure. This only works on the graphic state stack, however;
>          graphic state objects stored in VM would not be reset.

>          This is harmful only in a very obscure case when the charpath operator
>          is used on a user-defined font whose BuildGlyph procedure contains
>          internal save/restore operators and which builds part of its
>          output with the clippath operator. As far as we know, this has
>          never occurred in practice.

>       2. Several problems noted with files 119-01.ps (panel 119-07) and
>          119-28.ps (panel 119-31) were caused by a problem with the memory
>          allocator used for the jpeg_compress_data structure used with the
>          DCTEncode (JPEG) filter. This filter is used by the PDFwriter, the
>          JPEG device drive, and as a filter accessible from PostScript.
>          In the first two cases the jpeg_compress_data structure is allocated
>          using the normal, gs_ref_memory_t structure. When used from
>          PostScript, however, this structure is allocated using the
>          gs_memory_default allocator (presumably because the jpeg library
>          code is not set up to deal with save/restore).

>          The gs_memory_default allocator is not a gs_ref_memory_t allocator,
>          so it does not create the hidden obj_header_t structures preceding
>          each allocated region. The garbage collector is dependent on these
>          headers, hence the pointer enumeration routines in structure
>          descriptors must not enumerate any pointers to memory allocated
>          by non-gs_ref_memory_t headers.

>          This creates a difficult problem for the pointer enumeration
>          routine of the stream_DCT_state structure, whose data.compress field

>     The attached code release addresses a number of issues:

>       1. Most of the code changes are required to turn off overprint mode when

>          when using PatternType 2 (smooth shading) patterns.

>       2. A few other changes were required to correct improper updating of the

>          files such as mspro.pdf to be rendered consistently in the banded and

>                                                                     Jan

>     Modified Files:

>       lib/gs_img.ps
>         Added code to turn off overprint mode for images.

>       lib/gs_ll3.ps
>         Added code to turn off overprint mode for shfill.

>       src/gscolor2.c
>         1. Modified gs_setcolorspace to call gs_do_set_overprint rather than
>            invoking the color space's set_overprint routine directly. This
>            allows pattern color spaces to be handled (somewhat more) correctly.
>         2. Modified gs_setcolor to update overprint information. This is
>            necessary for pattern color spaces, where the color space to be used
>            for overprint purposes may be part of the color.

>       src/gscspace.c
>         Modified gx_set_overprint_DeviceCMYK to use the effective_overprint_mode
>         parameter in the image state (rather than the overprint_mode parameter
>         itself). This is part of the change necessary to allow overprint mode to
>         be turned off when a PatternType2 pattern is used as the current color.

>       src/gsdevice.c
>         Modified gs_set_device_no_init to call gs_do_set_overprint rather than
>         invoking the color space's set_overprint routine directly.

>       src/gsdps1.c
>         Modified rectfill to use the effective_overprint_mode parameter in the
>         imager state (rather than the overprint_mode parameter).

>       src/gsovrc.c
>         1. Fixed a bug in overprint_draw_thin_line: the third and fourth
>            operands in the call to gx_default_draw_thin_line (the y coordinate
>            of the first point and the x-coordinate of the second) were
>            in reverse order. This caused random lines to appear on various
>            overprint mode tests (e.g.: BEST99-00-Path.fh7.pdf,
>            Testform.v1.0.2.pdf).
>         2. Fixed typo in comment.
>         3. Modified the fill_in_procs procedure to initialize the device color
>            model information for the temporary device used in this routine.
>            Though the color model information does not affect the output of
>            the routine, reasonable values must be provided to avoid problems
>            when gx_device_forward_fill_in_procs calls gx_device_fill_in_procs.
>            This would cause certain systems to crash with files that involved
>            overprint/overprint mode (e.g.: 86554321.pdf on MSWinXP/MSVC systems).
>         4. Modified several checks that treated the separable_and_linear flag
>            in the device color model information as a boolean to handle this
>            parameter as an enumeration instead (since it is an enumeration).

>       src/gsptype1.c
>         Added gs_pattern1_set_color, the set_color method appropriate for
>         PatternType 1 patterns. This method performs overprint updating at
>         setcolor time, a requirement for patterns as the "colorspace" to be
>         used for overprint purposes is determined (in part) by the current
>         "color" (pattern).

>       src/gsptype2.c
>         Added gs_pattern2_set_color, the set_color method appropriate for
>         PatternType 2 patterns.

>       src/gsstate.c
>         1. Changed the criterion used in gs_grestore_only to determine if the
>            overprint compositor must be updated. Restoring the graphic state
>            may change the current color, which in the case of patterns may
>            change the "colorspace" to be used for overprint purposes. The code
>            now properly handles this possibility.
>         2. Added the gs_do_set_overprint routine, and modified various other
>            routines that directly call the current color space's
>            set_overprint method to call this procedure instead. The procedure
>            implements the special handling required for pattern color spaces,
>            where the current color may need to be considered when determining
>            which color model components must be retained.
>         3. Added code to initialize the effective_overprint_mode parameter in
>            the imager state, and provided two external routines to manipulate
>            this parameter. The first routine, gs_disable_effective_overprint_mode,
>            sets the effective_overprint_mode parameter to false, irrespective
>            of the setting of the overprint_mode parameter. The second,
>            gs_reset_effective_overprint_mode, sets the effective_overprint_mode
>            parameter to have the same value as the overprint_mode parameter.
>            The effective_overprint_mode parameter is used to turn off
>            overprint_mode when a PatternType 2 pattern is being used.

>       src/gsstate.h
>         Added prototypes for gs_do_set_overprint,
>         gs_disable_effective_overprint_mode, and
>         gs_reset_effective_overprint_mode.

>       src/gxccache.c
>         Modified gx_image_cached_char to invoke gx_set_dev_color before calling
>         (non-standard) device fill_mask methods. This handles several
>         situations in which a device color is not set when a cached character
>         is to be imaged, in particular for the command list device.

>       src/gxclpath.c
>         Added a comment to indicate that, though the overprint and
>         overprint_mode parameters are passed through the command list, they
>         usually have no effect, as overprint is controlled by the compositor
>         information that is (also) passed through the command list.

>       src/gxclrast.c
>         1. Added a comment to indicate that the overprint and overprint mode
>            parameters passed through the command list usually have no effect.
>         2. Added code to initialize the effective_parameter_mode field in the
>            imager state (though this field is usually in-effective).
>         3. Initialized the fill_zero_width field of the fill_params structure
>            in clist_playback_band to have the same value as in the noband case.
>            This parameter was previously always set to false, which led to
>            dropped lines for some files (e.g.: mspro.pdf).

>       src/gxistate.h
>         Added the effective_overprint_mode parameter.

>       src/gxpcolor.h
>         Added a set_color method to the pattern method vector. This method
>         performs any PatternType-specific actions necessary at setcolor
>         time. For now, this just updates the overprint compositor as required.

The script tries a variety of likely candidates for a 64-bit type and passes the first one found through the GCFLAGS makefile variable.

>     We have traced the difficulties with multiple-band processing in the code
>     we released on Aug. 26 to two problems:

>       1. The halftone phase information is not adjusted for bands that
>          start at locations other than the top of the page.

>       2. The "moveto closepath" style of degenerate path, which our code
>          allows to be passed through the band list, is used in the path
>          encoding code to indicate that a path lies entirely outside the
>          current band (i.e.: all of the path operators between the initial
>          moveto and the final closepath have been skipped because they are
>          outside of the band). This resulted in the code passing isolated
>          "closepath" segments through the command list, which much confused
>          the band list renderer.

>     The attached code release fixes both of these problems, and a couple of
>     other more minor issues we discovered. With this change, our system has

>     of the other devices in the next day or so.

>     As best we can tell, halftone phase adjustment has never been correctly
>     implemented for the command list device. The pre-DeviceN code handles
>     binary halftone colors properly, but does not set the phase for general
>     colored halftones. General colored halftones are much more common in the

>       src/gxclpath.h
>         1. Added the cmd_opv_ext_put_ht_seg, to allow device halftones to be

>        unnecessary, and none of the three implementors of the xfont interface

>        COMPATIBLE change for all clients of the glyph_name and known_encode
>        procedures (of which there are, respectively, 11 and 0 in the current
>        code base), and for all places that define gs_font_procs structures
>        statically or initialize the callbacks dynamically (of which there are
>        currently only two, one in gsfont.c and one in zbfont.c).  There are also

>        plufont.c) that will require very minor changes, with a small net
>        reduction in code.

>     2) Deletes the char_xglyph2 procedure from gx_xfont_procs.  It is optional,
>        and none of the three current xfont implementations implements it.

>     3) Changes the char_xglyph procedure in gx_xfont_procs so that instead of a
>        glyph_name callback procedure, it takes a const gs_string * argument that
>        is the actual glyph name (if the glyph is not gs_no_glyph and is not a
>        CID).  This is a NON-BACKWARD-COMPATIBLE change for both clients and

>        which use the glyph_name callback, and a single client call in
>        gxccache.c.)

>     4) Moves the glyph_name procedure, which is still required for other
