fixed a dangling pointer bug that happened in very rare cases:
i.e. when a new family object was destroyed by an out-of-memory
condition during a glyph node initialization. The function
FTC_Cache_Lookup would flush the cache and restart the lookup
with a bad pointer.
* src/cache/ftcmanag.c: fixed a cache flushing bug
* src/pcf/pcfutil.c: Use FT_LOCAL_DEF.
* src/pcf/pcfutil.h: Include FT_CONFIG_CONFIG_H.
Use FT_BEGIN_HEADER and FT_END_HEADER.
Use FT_LOCAL.

to convert them to (gindex,gindex) !
* include/freetype/ftoption.h: commenting out the macro
TT_CONFIG_OPTION_BYTECODE_INTERPRETER
include/freetype/internal/ftobjs.h, include/freetype/internal/tttypes.h,
src/truetype/ttinterp.c, src/truetype/ttobjs.c, src/truetype/ttobjs.h:
changed the name of TT_CONFIG_OPTION_COMPILE_UNPATENTED_HINTING to
the simpler TT_CONFIG_OPTION_UNPATENTED_HINTING
removed the macro TT_CONFIG_OPTION_FORCE_UNPATENTED_HINTING. Instead,
the same effect can be used by setting a debug-hook with
FT_DEBUG_HOOK_UNPATENTED_HINTING globally with FT_Set_Debug_Hook()
[TT_CONFIG_OPTION_BYTECODE_INTERPRETER]: Call
FT_GlyphLoader_CheckPoints before adding phantom points. This fixes
a segfault bug with fonts (e.g. htst3.ttf) which have nested
subglyphs more than one level deep. Reported by Anthony Fok.
* include/freetype/config/ftoption.h: Define
TT_CONFIG_OPTION_BYTECODE_INTERPRETER,
TT_CONFIG_OPTION_COMPILE_UNPATENTED_HINTING, and
TT_CONFIG_OPTION_FORCE_UNPATENTED_HINTING to make it the new
default.
* include/freetype/config/ftoption.h [FT_CONFIG_OPTION_MAC_FONTS]:
New macro.
* src/base/ftobjs.c: Use it to control mac font support on non-mac
platforms.
Implement partial support of Mac fonts on non-Mac platforms.
* src/base/ftobjs.c (memory_stream_close, new_memory_stream,
open_face_from_buffer, Mac_Read_POST_Resource,
Mac_Read_sfnt_Resource, IsMacResource, IsMacBinary, load_mac_face)
[!FT_MACINTOSH]: New functions.
(FT_Open_Face) [!FT_MACINTOSH]: Use load_mac_face.
* src/base/ftobjs.c (FT_Load_Glyph): Scale linear advance width only
if FT_FACE_FLAG_SCALABLE is set (otherwise we have a division by
zero since FNT and friends don't define `face->units_per_EM').
* include/freetype/config/ftoption.h, src/autohint/ahglobal.h,
src/autohint/ahglobal.c, src/autohint/ahglyph.c,
src/autohint/ahtypes.h:
included David Chester's patches to the auto-hinter in order to
slightly improve the output. Note that everything is controlled
through the new FT_CONFIG_OPTION_CHESTER_HINTS defined at the
end of "ftoption.h", there are also individual FT_CONFIG_CHESTER_XXX
macros to control individual "features".
Note that all improvements are enabled by default, but can be
tweaked for optimization and testing purpose. The configuration
macros will most likely disappear in the short future.
2003-01-11 David Turner <david@freetype.org>
* include/freetype/internal/fnttypes.h: fixed a structure field
definition to avoid memory overwrites
* 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
parameter sign-ness in callback function
* include/freetype/config/ftmodule.h,
include/freetype/internal/fttrace.h,
src/Jamfile, src/pfr/*:
adding a PFR font driver to the FreeType sources. Not that it
doesn't support embedded bitmaps or kerning tables for now..
* include/freetype/internal/ftmemory.h: adding the FT_MEM_ZERO
and FT_ZERO macros
* include/freetype/internal/ftstream.h: adding the FT_NEXT_OFF3,
FT_NEXT_UOFF3, FT_NEXT_OFF3_LE and FT_NEXT_UOFF3_LE to parse
in-memory 24-bit integers.
FT_LOCAL and FT_LOCAL_DEF, respectively, as with other ftconfig.h
files.
* builds/unix/ftconfig.in: Add argument to FT_LOCAL and
FT_LOCAL_DEF.
* src/truetype/ttinterp.c: s/FT_Assert/FT_ASSERT/.
* builds/unix/configure.ac: Temporarily deactivate creation of
../../Jamfile.
* builds/unix/configure: Updated.
the debug sub-system initialization. trace levels can now be specified
within the "FT2_DEBUG" environment variable. See the comments within
"ftdebug.c" for more details
* include/freetype/internal/fttrace.h: new file to define the trace
levels used for debugging. it is used both to define enums and
toggle names for FT2_DEBUG
* src/base/ftobjs.c, src/base/ftstream.c: FT_Assert renamed to
FT_ASSERT
* include/freetype/internal/ftextend.h, src/base/ftextend.c,
src/base/Jamfile, src/base/rules.mk: removing "ftextend" from the
library, since it is now completely obsolete..
constant with a fixed-float equivalent. For some reason, some compilers
aren't capable of directly computing a floating pointer constant casted
to FT_Fixed, and will link a math library instead !!
some of the exported functions should only be used by applications
that need to implement custom cache types
* src/truetype/ttgload.c: fixed a nasty bug that prevent composites
from loading correctly. Believe it or not, this was due to an invalid
macro definition !!
