function violates the layering of the interpreter over the graphics library.
Therefore we isolate the offending code to a separate module 'macpoll.dev'
in a fashion analogous to the mspoll feature dev available on the windows
build. Enable this by default in the CodeWarrior build.
Partial fix for Bug 686810. After a patch by Russell Lang.

timeslice code. This allows a client to abort the interpreter
when running "{} loop". Fixes Bug 686810 "CHECK_INTERRUPTS
should allow shorter worst-case abort".
DETAILS:
PostScript which executed an infinite loop could not be stopped
by the gsapi client. The time slice code in the main
interpreter loop is executed once for every 32767 passes through
the interpreter loop. Within the time slice code we now call
the polling function and if the return value is non-zero, we set
code to gs_error_interrupt to cause the interpreter to exit.
This was not a client bug (as far as I know). The original
request was from Zoltan Biro.

under CodeWarrior.
DETAILS:
The jbig2dec library and headers require some of the C99 types. We've
made sure those are available, but the mechanism depended on either
passing -DHAVE_STDINT_H on the commandline or windows-specific typedefs.
Since there's no convenient way pass single defines through codewarrior
that would be seen by both the jbig2dec and the gs sources, we add a
platform-specific define to headers in each codebase.

DETAILS:
This is really just a quick fix; it doesn't check flags for the debug or profile
builds. A full solution would also try known options based on the compiler
being used. It's not fair to just disable optimization if -O2 doesn't work.

DETAILS:
This patch mixes 3 changes :
1. Applying a compression to vector charprocs. Bitmap charprocs are
left uncompresed. The written PDF should have same contents as before.
2. A preparation to Type 1 pattern accumulation with implementing
a pdf_substream_save stack. Moved accum_char_proc_* fields to there.
This change should be equivalent.
3. Renamed cos_write_stream_from_pipeline to cos_stream_from_pipeline,
because the old name appears confusable.
A new function with the old name is defined for another purpose.
No regression changes expected.

pdfwrite crashes with -r72 012-09.ps due to 2 nesting separates :
one for charproc accumulator, and another one for graphic state object inside it.
This problem does not happen with comparefiles with the default value of -r.
Meanwhile the problem is harmful because it occasionally depends on CTM.
Minor changes :
- A misprint in "pdf_begin_char_proc_gerneric".
- Removed some unused variables.
- Inserted some necessary #include statements.

DETAILS:
In some cases the scanline algorithm appears to speed up the sfill in about 2 times.
This patch enables the scanline algorithm when DROPOUT_PREVENTION is on,
except for characters. It brings the shfill case closer to the old algorithm.
This patch causes minor differences while filling a path,
especially with shfill, but such differences should be small
and almost unvisible.
Minor change :
The condition in gxfill.c line 2075 is changed to be closer to
the old algorithm when filling non-characters, because
dropout prewvention is not neccessary for this case.

Bug 686807 A "subset fonts" error in Adobe Acrobat from files made by GS8.00
DETAILS :
Since the revision 1.9 of gdevpdtb.c (Sun Sep 8 20:20:12 2002 UTC)
subset font names were deterministic to simplify the debugging.
The names were derived from resource IDs, and could cause a conflict
when merging documents. This patch generates different font names
hashing the glyph usage bitmask. Now the conflict can happen
with a very small probablility, when different subsets give same
hash value.

THIS IS INCOMPATIBLE CHANGE, because the default resource path is now different :
resource files are moved to gs/Resource .
See gs/doc/Use.htm#Finding_files and gs/doc/Use.htm#Resource_related_parameters.
DETAILS:
This patch does not include necessary changes to Ghostscript installer.
The main code change in one to gp.h .
Rudiments of old code in gs/src and gs/lib are marked with NEW_COMBINE_PATH.
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 :
<string> <string> <bool> .file_name_combine <string> true
<string> <string> <bool> .file_name_combine <string> <string> 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 <bool> 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 <bool> 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 <string>
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 <string>
Returns a readonly string, which represents a separator
which is used in file names between two directory items.
Used for making the default value of GenericResourceDir
and FontResourceDir.
- .file_name_current <string>
Returns a readonly string, which represents a reference
to current working directory. Used for making the default
value of GenericResourceDir and FontResourceDir.

This should work on all supported platforms and seems to be the only way
to get the file type using a MSVC CRTL function.
Bug #686773
DETAILS:
Windows API documentation seems to imply undefined results when seeking
of retrieving file position of a special file. MSDN documentation requires
programmers to check file type using GetFileType() function before seeking.
MSVC 6 CRTL doesn't check file type before calling the corresponding
Windows API functions. fstat() is the only function in MSVC 6 CRTL that
calls GetFileType(). S_ISREG() is a POSIX macro that check whether the
file is ordinary. It can be easily emulated if missing.

format. Accepts xml input from the cvs2cl perl script.
DETAILS:
After the 8.00 release we switched to a new format for Changes.htm and the
History files, based on the more traditional Changelog format instead of
grouping commits by section, which often resulted in duplicate posts. At
the same time we began a convention of including any notes too extensive
for such a listing below a 'DETAILS:' separator, with the idea that we'd
create two changelogs, with hyperlinks between so detailed information was
still available even in the new easier to browse format.
The method we've adopted uses the cvs2cl perl script, available from
http://www.red-bean.com/cvs2cl/ to parse the output of 'cvs log' and
generate an xml file containing the merged entries. This script is
more robust than our own cvs2hist. The split_changelog.py script is
then run to convert the xml changelog to the two sizes of linked html

Bug 686812 "Incorrect font rendering for Zapfino ampersand".
DETAILS :
It always restricted overshoots with 1 pixel due to a stupid error in code.
This patch causes differences in almost tests with 300 dpi,
and with 3 tests at 72 dpi.
