>     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.

>     Convert ASCII range font names found during the FONTPATH scanning to
>     simole ASCII aliases (original Unicode names preserved). Fixes bug 686861
>     for customer 131.

>     DETAILS:

>     This is an interim patch that establishes the alias in the ASCII code
>     range if (and only if) the high byte of ALL characters in the name are
>     NULL (\000).

>     The future improved implementation would be to add a UTF-8 fontname when
>     the TTF font has the name in Unicode. This would allow simple PostScript

>     Pass path across grestore using base "identity" coordinates to prevent

>     "grestore" or "setgstate" causes. Fixes SF bug #687001 for customers
>     580 and 590.

>     restoring the CTM of the grestore after the uappend.

>     Both grestore_nopath and setgstate are modified. These could probably

>     DETAILS:

>     With some test files, saved graphics states had held on to pointers to

>     actually freed until the last reference is dropped.

>     A similar but simpler argument applies to the pdf14_ctx object in the
>     pdf14_device. This patch simply sets the pointer to NULL when freeing

>     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

>     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.

>     A pair of fixes for Bug 686791   Device bitcmyk produces wrong output
>     The bitcmyk device produce the wrong output if GrayValues=8.  In this
>     case the pixel size is 32 bits.  The encode_color procedure was sign
>     extending the  MSB into the upper 32 bits of 64 bit gx_color_indexes.
>     The fix in gdevbit.c prevents this from happening.  The fix in gdevm32.c
>     makes it so that it does not matter.  I am including both for
>     completeness.  The bitcmyk device should not produce garbage in the
>     remaining bits.  Thus the first fix.  However there may be other
>     devices with this problem so I am including the fix in gdevm32.c.
>     There was a recent report from an AIX system with a similar problem

>     DETAILS:

>     The stream position was not updated if the buffer was emptied by

>     DETAILS :

>     The previous patch appears wrong for the case when same CID font is used with
>     different CMaps. Creating multiple Type 0 fonts for this case,
>     assigning them a composite font name with CMap name.

>     Minor changes :

>     - a compiler warning in gdevpdfv.c .

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

>     DETAILS :

>     Bug 686869 "Rasterized characters".

>     Our testbase doesn't test this case. Rather the test file for 686869
>     contains a font with 2 CID descendents, it actually uses only the 1st
>     descendent, so it's not a complete test.

>     The new code fails with 401-01.ps . This test file is buggy and
>     requires a special workaround, which should be a separate patch.

>     The main change is gdevpdtc.c, gdevpdtf.h .

>     Minor changes :

>     - added a new argument to a set of CMap management functions to access a
>       submap corresponding to a specified font index;

>     - gs_cmap_init now reserves so many gs_id numbers,
>       as many fonts it refer;

>     - removed some unused variables (gdevpdfm.c, gdevpdfv.c, gdevpdtb.c).

>     DETAILS :

>     This change is algorithmically equivalent.

>     Note that 'size' argument is replaced with 'bsize', which now passes the
>     buffer size rather than text size. Added some dynamical checks to ensure the
>     buffer size is enough.
