PSSRC files are now in 'gs/psi'.
GLSRC files are now in 'gs/base'.
This is to facilitate build modularization and merging in the ghostpdl
tree.
NOTE: msvc32.mak is now in psi, not src.

DETAILS:
This patch allows to compile Ghostscript in a way that the X11 screen
display output devices can be seperated into a dynamically linkable
library, so that these devices can be put in a separate binary package
in Linux distributions. This way the distributions can be installed
with GhostScript and without the X libraries, which is important for
headless print servers.
This feature is only available for Unix with GCC (selected by the
Makefile).
Ghostscript will be compiled without built-in X11 support and with an
extra X11.so file containing the X11 support. One can install
Ghostscript with or without X11.so then, it will always work. It
detects the presence of X11.so automatically and makes the X11 output
devises available if X11.so is present (see "gs -h").
Small disadvantage: With modularized X11 support the "x11" device will
not stay the default one. "bbox" will be the default then. Use "gs
-sDEVICE=x11 ..." then.
This patch is used since mid 2001 in ESP Ghostscript and has never
caused any problems or bugs related to the modularization.
EXPECTED DIFFERENCES:
None (in the non-interactive automated regression tests)

DETAILS :
This is a preparation for a fix for
bug 688394 "clist playback of large pdf image segfaults".
This is a preliminary implementation.
Now it compiles for MSVC8, Linux/gcc .
For other platforms/compilers it is stubbed with 32 bits file access.
This patch requires to define -D_FILE_OFFSET_BITS=64 -D_LARGEFILE64_SOURCE
compiler options on Linux in Makefile .
We could not figure out why Cygwin/gcc defines fopen64, ftello64, fseeko64,
and then cannot link them. We didn't find imlementations of those functions
in C libraries.
EXPECTED DIFFERENCES :
None.

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.
Improvements and implementations for other platforms are to follow.

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.

iodevice for
retrieving data from the 'resource' structure associated with MacOS files, either directly from
the resource fork, or from a serialized data fork resource file. This is primarily used to access
font data on that platform. Resource fork access is only supported on MacOS, while data fork files
(e.g. .dfont format font files) can be read on any platform. This code is currently disabled.
DETAILS:
This change allows fonts stored in resources to be specified in the fontmap. A special indexing
scheme is added to the filename to address the particular resource desired by id and 4-character
type code, e.g. '%macresource%Arial#sfnt+4096' or
'%macresource%/Library/Fonts/Optima.dfont#sfnt+14151'.

gs_exit() is renamed gs_to_exit() since it is an about to terminate cleanup
function, it always returns.
Both gs_to_exit() and gs_abort are client provided functions. The client
can have its own special cleanup on exit, and the client can decide what it
wants to do in the abort case: exit, setjump/longjump, ...
gp_do_exit() is the way for the client to call a system independent exit()
this allows for different exit codes on unix and vms for instance.
Only the client can call this, if so desired from their gs_abort().

each file is checked in with an associated log entry, in order to
check in all of the code simultaneously we batch all of the file
name's modified and change descriptions here (Note: Aladdin code changes
are documented in gs/doc/News.htm)
- pcstate.h - removes show enumeration from pcl state.
- pctop.c, pxtop.c
- gs_grestore_no_wraparound()'s is now gs_grestore_only().
- pxgstate.c
- ENUM_RETURN_CONST_STRING_PTR() now takes a gs string
argument instead of the string's data as it did
previously.
- plmain.c -
- The library no longer initializes io devices. Adds
gs_iodev_init() to main() procedure. Also, gs_c_param_list_rewrite()
is renamed to gs_c_param_list_write_more().
- pcltop.mak - adds pipe.dev for operating system pipe support.
- pctext.c, pglabel.c, pxfont.c, plfont.c
- extensive modifications to support the text api (gstext.h)
- use gs_text_enum_t instead of gs_show_enum.
- removes enumeration allocation, this is now done by the text
"begin" functions.
- update "next_char" procs and "encode char" procs to take a
glyph argument and the character argument is now passed by value
(pcl nor xl make use of the glyph argument).
- char_path_n_init() replaced with gs_charpath_begin().
- gs_show_n_init() replaced with gs_show_begin().
- gs_show_next() is now handled by gs_process_text().
- gs_release_text() added.
- gs_xyshow_n_init() replace with gs_xyshow_begin(). Passing
of x and y coordinates modified to support the new interface.
Unfortunately, we need to transform the coordinates into the
space of the font scaling matrix, that is the current ctm for
xl when the the text is processed. This differs from postscript
which appears to have the regular user->device matrix in the
graphics state during processing.
- (plfont.c) - gs_notify_init() is now part of the pfont
initialization procedure, related TODO: cut over to gs_font_alloc()
and gs_font_base_alloc().
- all gs files - removes uninitialized rcs identifiers.
KNOWN PROBLEMS:
occassional pxl and pcl crashes in gdev_mem_set_line_ptrs() when
running in color due to null base (data) pointer.
