Previously, signed integers were converted to unsigned integers, but
this can fail because of sign extension. For example, 0xa344a1eb
becomes 0xffffffffa344a1eb.
We now do the reverse which is always correct because the integer
size is the same during the cast from unsigned to signed.
* include/freetype/internal/ftstream.h, src/base/ftstream.c
(FT_Stream_Get*): Replace with...
(FT_Stream_GetU*): Functions which read unsigned integers.
Update all macros accordingly.
* src/gzip/ftgzip.c (ft_gzip_get_uncompressed_size): Updated.
src/autofit/afcjk.c, src/autofit/afhints.c, src/autofit/aflatin.c,
src/autofit/aftypes.h, src/base/ftcalc.c, src/base/ftoutln.c,
src/gzip/ftgzip.c, src/psaux/psconv.c, src/truetype/ttgload.c,
src/type1/t1gload.c:
this is a major patch used to drastically improve the performance
of loading glyphs. This both speeds up loading the glypn vector
themselves and the auto-fitter.
note that we've started using inline assembler with GCC to
implement FT_MulFix, given that this function is so damn
important for the engine's performance.
the resulting speed-up is about 25%.

* include/freetype/config/ftstdlib.h (FT_CHAR_BIT, FT_FILE,
ft_fopen, ft_fclose, ft_fseek, ft_ftell, ft_fread, ft_smalloc,
ft_scalloc, ft_srealloc, ft_sfree, ft_labs): New wrapper macros for
C library functions. Update all users accordingly (and catch some
other places where the C library function was used instead of the
wrapper functions).
* src/base/ftsystem.c: Don't include stdio.h and stdlib.h.
* src/gzip/zutil.h [MSDOS && !(__TURBOC__ || __BORLANDC__)]: Don't
include malloc.h.
the warp hinter isn't active (it shouldn't, still experimental)
* Jamfile, include/freetype/config/ftmodule.h: removed "gxvalid"
and "otvalid" from the list of modules that are linked statically
to a given FreeType library. Functionality has been moved to the
"ftvalid" CVS module.
note also that current Make-based build system still compiles the
modules though...
* include/freetype/config/ftoption.h: added FT_STRICT_ALIASING,
which controls the definitions of the memory management functions
to avoid warnings with recent versions of GCC. this macro is
only here to be disabled, in case we detect problems with the
new scheme.
NOTE: disable macro to use the memory debugger. this will be fixed
later !!
used to reduce the amount of heap size required to only test wether
we're dealing with a BDF font (the old code allocated 64 Kb right
before any test).
* src/lzw/ftlzw.c (FT_Stream_OpenLZW): modified the function to check
the LZW header before doing anything else. This helps avoid un-necessary
heap allocations (400 Kb of heap memory for the LZW decoder ! Oh my !)
* src/gzip/ftgzip.c (FT_Stream_OpenGZip): ditto for the .gz decoder,
though the code savings is smaller.
* include/freetype/internal/cfftypes.h, src/cff/cfftypes.h,
src/cff/cffload.h, src/cff/cffobjs.h, src/cff/cffparse.h,
include/freetype/internal/services/svbdf.h: moving "cfftypes.h" from
'include/freetype/internal' to 'src/cff' since no other modules needs
to known about these types
* include/freetype/internal/t42types.h,
include/freetype/internal/internal.h, src/type42/t42objs.h,
src/type42/t42drivr.c, src/type42/t42types.h: moving "t42types.h" from
'include/freetype/internal' to 'src/type42' since no other modules needs
to known about these types
* src/gzip/infblock.c: removing compiler warning
* include/freetype/internal/services/svpsinfo.h,
include/freetype/internal/ftserv.h, src/cff/cffdrivr.c,
src/cid/ciddrivr.c, src/type1/t1driver.c, src/type42/t42drivr.c,
src/base/fttype1.c: migrating to FT_SERVICE_ID_POSTSCRIPT_INFO defined
in "svpsinfo.h", removing some sad hacks.

(inflate_trees_fixed): Decorate with more `const' to avoid
writable global variables which are disallowed on ARM.
computation of glyph_index.
(FNT_Size_Set_Pixels): To find a strike, first check pixel_height
only, then try to find a better hit by comparing pixel_width also.
Without this fix it isn't possible to access all strikes.
Also compute metrics.max_advance to be in sync with other bitmap
drivers.
* src/base/ftobjs.c (FT_Set_Char_Size): Remove redundant code.
(FT_Set_Pixel_Size): Assign value to `metrics' after validation of
arguments.
Synchronize computation of height and width for bitmap strikes. The
`width' field in the FT_Bitmap_Size structure is now only useful to
enumerate different strikes. The `max_advance' field of the
FT_Size_Metrics structure should be used to get the (maximum) width
of a strike.
* src/bdf/bdfdrivr.c (BDF_Face_Init): Don't use AVERAGE_WIDTH for
computing `available_sizes->width' but make it always equal to
`available_sizes->height'.
* src/pcf/pcfread.c (pcf_load_font): Don't use RESOLUTION_X for
computing `available_sizes->width' but make it always equal to
`available_sizes->height'.
* src/truetype/ttdriver.c (Set_Pixel_Sizes): Pass only single
argument to function.
* src/psnames/psmodule.c (ps_unicode_value): Handle `.' after
`uniXXXX' and `uXXXX[X[X]]'.

variables to the beginning of the function to avoid compiler
problems.
Add casts necessary for 16bit compilers.

(pfr_lookup_bitmap_data): Change type of third and fourth argument
to FT_UInt. Updated caller.
(pfr_load_bitmap_bits): Change type of fourth argument to FT_Bool.
. In all makefiles `/' is used as the path separator. The
conversion to the real path separators is done as late as
possible using $(subst ...).
. $(HOSTSEP) no longer exists. Now, $(SEP) gives the path separator
for the operating system, and the new $(COMPILER_SEP) the path
separator for the compiler tools.
. $(BUILD) has been renamed to $(BUILD_DIR). In general, all
directory variables end with `_DIR'. The variants ending in `_'
(like `BASE_' have been removed).
The following ChangeLog entries only describe changes which are
not related to the redesign.
* builds/beos/beos-def.mk (BUILD_DIR): Fix typo.
* builds/compiler/watcom.mk (LINK_LIBRARY): Fix linker call to avoid
overlong arguments as suggested by J. Ali Harlow
<ali@avrc.city.ac.uk>.
* builds/dos/dos-wat.mk: New file.
* builds/freetype.mk (FREETYPE_H): Include header files from the
`devel' subdirectory.
* builds/os2/os2-dev.mk, builds/unix/unixddef.mk,
builds/unix/unixddef.mk, builds/win32/w32-bccd.mk,
builds/win32/w32-dev.mk (BUILD_DIR): Fix path.
* builds/unix/configure.ac, builds/unic/configure: Updated.
* builds/unix/unix-def.in (DISTCLEAN): Add `freetype2.pc'.
* devel/ftoption.h: Updated.
make it compile.
* include/freetype/internal/psaux.h, src/truetype/ttgload.h:
s/index/idx/ to fix compiler warnings.
* src/sfnt/ttcmap0.c (tt_face_build_cmaps): Use more `volatile' to
fix compiler warning.
* src/gzip/ftgzip.c (BUILDFIXED): Removed.
* src/gzip/inftrees.c (inflate_trees_fixed) [!BUILDFIXED]: Use
FT_UNUSED to remove compiler warning.
* src/gzip/ftgzip.c (ft_gzip_file_io): Avoid zero value of `delta'
to prevent infinite loop.
* docs/VERSION.DLL: Provide better autoconf snippet to check
FreeType version.
* src/base/ftobjs.c (open_face): Free `internal' not
`face->internal' in case of error to avoid possible segfault.
* src/pshinter/pshalgo3.c (ps3_hints_apply): Check whether we
actually have an outline.
argument.
(bdf_get_font_property): Use `const' for third argument.
Updated all callers.
* src/bdf/bdfdrivr.c (BDF_Face_Init): Set pixel width and height
similar to the PCF driver.
* src/bdf/bdf.h (_hashnode): Use `const' for `key'.
Updated.
* src/gzip/ftgzip.c: C++ doesn't like that the array `inflate_mask'
is declared twice. It is perhaps better to modify the zlip source
files directly instead of this hack.
(zcalloc, zfree, ft_gzip_stream_close, ft_gzip_stream_io): Add casts
to make build with g++ successful.
when trying to read certain compressed gzip files. The following test
could be used to reveal the bug:
touch 0123456789 ; gzip 0123456789 ; ftdump 0123456789.gz
* src/pfr/pfrobjs.c, src/pfr/pfrload.c, src/pfr/pfrtypes.h: several
fixes to the PFR font driver:
- the list of available embedded bitmaps was not correctly set
in the root FT_FaceRec structure describing the face
- the glyph loader always tried to load the outlines when
FT_LOAD_SBITS_ONLY was specified
- the table loaded now scans for *undocumented* elements of a
physical font's auxiliary data record, this is necessary to
retrieve the "real" family and style names.
NOTE THAT THIS CHANGES THE FAMILY NAME OF MANY PFR FONTS !!
src/gzip/inftrees.c, src/gzip/zconf.h, src/gzip/zlib.h,
src/gzip/zutil.h: updates to allow compilation without compiler
warnings with LCC-Win32
* include/freetype/freetype.h, docs/VERSION.DLL,
builds/unix/configure.ac: updates for the upcoming 2.1.4 release
* docs/VERSION.DLL: updating document to better explain the differences between
the three version numbers being used on Unix, as well as provide the AutoConf
fragment provided by Lars Clausen
* src/smooth/ftgrays.c (gray_render_conic): fixed small bug that
prevented bezier arcs with negative vertical coordinates to be rendered
appropriately
2002-11-27 Vincent Caron <v.caron@zerodeux.net>
* builds/unix/unix-def.in, builds/unix/freetype-config.in,
builds/unix/configure.ac, src/gzip/rules.mk, src/gzip/ftgzip.c:
adding support for system zlib installations when available on the
target platform (Unix only)
* include/freetype/config/ftoption.h, src/gzip/ftgzip.c: added
support for the FT_CONFIG_OPTION_SYSTEM_ZLIB option, used to specify
the use of system-wide zlib.
Note that this macro, as well as FT_CONFIG_OPTION_BYTECODE_INTERPRETER,
is not #undef-ed anymore. This allows the build system to define them
depending on the configuration (typically by adding -D flags at
compile time).
* src/sfnt/ttcmap0.c (tt_face_build_cmaps): removed compiler warnings
in optimized mode relative to the "volatile" local variables. This was
not a compiler bug after all, but the fact that a pointer to a volatile
variable is not the same than a volatile pointer to a variable :-)
the fix was to change "volatile FT_Byte* p"
into "FT_Byte* volatile p"
* src/pfr/pfrload.c, src/pfr/pfrdrivr.c, src/gzip/inftrees.c: removed
compiler warnings in optimized modes
* src/gzip/*.[hc]: modified our ZLib copy in order to prevent exporting
any zlib function names outside of the component. This prevents linking
problems on some platforms, when applications want to link FreeType
_and_ ZLib together.
2002-11-05 Juliusz <jch@pps.jussieu.fr>
* src/psaux/psobjs.c (ps_table_add): modified increment loop in
order to implement exponential behaviour
