include/freetype/internal/ftmemory.h, src/base/ftdbgmem.c,
src/base/ftutil.c: udpating the memory management functions and
macros to safely deal with array size buffer overflows, this
corresponds to attemps to allocate arrays that are too large. For
an example, consider the following code:
count = read_uint32_from_file();
array = malloc( sizeof(Item) * count );
for ( nn = 0; nn < count; nn++ )
array[nn] = read_item_from_file();
if 'count' is larger than FT_UINT_MAX/sizeof(Item), the multiplication
will overflow and the array allocated will be smaller than the data
read from the file. In this case, the heap will be trashed, and this
can be used as a denial-of-service, or make the engine crash later.
the FT_ARRAY_NEW and FT_ARRAY_RENEW macro now check that the new
count is no more than FT_INT_MAX/item_size, otherwise, a new error,
named 'FT_Err_Array_Too_Large' will be returned.
note that the memory debugger now works again when FT_DEBUG_MEMORY
is defined, and FT_STRICT_ALIASING has disappeared, the corresponding
code being now the default.

sufficient to modify a single file, `modules.cfg', to control the
inclusion of modules and base extension files.
This change also fixes the creation of ftmodule.h; it now depends on
`modules.cfg' and thus is rebuilt only if necessary.
Finally, a version of `ftoption.h' in OBJ_DIR is preferred over the
default location.
* modules.cfg: New file.

a phony prerequisite which is run only if the target file must be
rebuilt (phony prerequisites act like subroutines and are *always*
executed). We only want to rebuild `ftmodule.h' if `module.cfg' is
changed.
Update all callers.

`modules.cfg'.
* builds/toplevel.mk: Rewrite and simplify module handling.

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

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()
correctly.
* src/pshinter/pshglob.c (psh_globals_new): Change calculation of
dim->stdw.count to avoid compiler problem.
* src/truetype/ttgload.c (TT_Load_Simple_Glyph): Move the block
variables to the beginning of the function to avoid compiler
problems.
Add casts necessary for 16bit compilers.
* src/pfr/rules.mk (PFR_DRV_SRC): Add pfrsbit.c.
(PFR_DRV_H): Add pfrtypes.h.
* include/freetype/config/ftconfig.h: s/__MWKS__/__MWERKS__/.
* src/pfr/pfrsbit.c (pfr_bitwriter_init): Change type of third
argument to FT_Bool.
(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.
[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/ftwinfnt.h, src/base/winfnt.c, src/winfonts/winfnt.c,
src/base/Jamfile, src/base/rules.mk, src/base/descrip.mms:
added a Windows .FNT specific API (mostly for Wine). Also fixed a nasty
bug in the header loader which would cause invalid memory overwrites
* 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
src/base/ftpfr.c, src/base/Jamfile, src/descrip.mms, src/rules.mk,
src/pfr/pfrdrivr.c, src/pfr/pfrobjs.c, src/pfr/pfsobjs.h:
added PFR-specific public API. Fixed the kerning retrievel routine
(it returned invalid values when the outline and metrics resolution
differ)
* src/base/ftsynth.c: fixed the synthetic emboldener. at last.
* src/base/ftobjs.c: small internal fix to better support
bitmap-based font formats
include/freetype/config/ftmodule.h: updated to correctly support
sub-pixel rendering
* include/freetype/cache/ftcimage.h, include/freetype/cache/ftcsbits.h,
src/cache/ftcimage.c, src/cache/ftcsbit.c: updated to support sub-pixel
rendering correctly. Definition of FTC_ImageTypeRec that replaces the
obsolete FTC_ImageDesc, and has slightly different fields. The
image type is now determined directly by "load_flags" values.
* src/autohint/ahtypes.h, src/autohint/ahhint.c,
src/pshinter/pshalgo3.c, src/pshinter/pshalgo3.h: various enhancements
to the automatic and Postscript hinters !! and sub-pixel hinting now
works correctly (see demo programs)
preferences. The header freetype.h is not now affected, the interface is
specified via an FT_Parameter, the pointer to the interface is hidden in an
internal part of the face record, and all the definitions are in ftincrem.h.
FT_Get_X11_Font_Format to return an X11-compatible string describing the
font format of a given face. This was put in a new optional base source
file, corresponding to a new public header (named FT_XFREE86_H since
this function should only be used within the XFree86 font server IMO).
* include/freetype/config/ftheader.h: adding FT_XFREE86_H, though it's
not documented yet.
* include/freetype/t1tables.h, src/base/fttype1.c: adding two new APIs
named "FT_Get_PS_Font_Info" and "FT_Has_PS_Glyph_Names". This required
a new optional source in 'src/base' named "fttype1.c"
* src/base/Jamfile, src/base/rules.mk, src/base/descrip.mms: updating
build control files for the new files "ftxf86.c" and "fttype1.c" in
src/base
(parse_font_matrix): Remove unnecessary code.
(parse_sfnts): Initialize some variables.
(t42_driver_class) [TT_CONFIG_OPTION_BYTECODE_INTERPRETER]: Use
ft_module_driver_has_hinter conditionally.
Moved some type 42 specific structure definitions to...
* include/freetype/internal/t42types.h: New file.
* include/freetype/internal/internal.h (FT_INTERNAL_T42_TYPES_H):
New macro.
* include/freetype/cache/ftcsbits.h (FTC_SBit): Added a new field
`num_grays' for specifying the number of used gray levels.
* src/cache/ftcsbits.c (ftc_sbit_node_load): Initialize it.
Adding a driver for BDF fonts written by Francesco Zappa Nardelli
<Francesco.Zappa.Nardelli@ens.fr>. Heavily modified by me to
better adapt it to FreeType, removing unneeded stuff. Additionally,
it now supports Mark Leisher's BDF extension for anti-aliased
bitmap glyphs with 2 and 4 bpp.
* src/bdf/*: New driver.
* include/freetype/internal/bdftypes.h: New file.
* include/freetype/internal/fttrace.h: Added BDF driver components.
* include/freetype/fterrdef.h: Added error codes for BDF driver.
* include/freetype/config/ftmodule.h, src/Jamfile: Updated.
* include/freetype/internal/internal.h (FT_INTERNAL_BDF_TYPES_H):
New macro.
* include/freetype/config/ftstdlib.h (ft_sprintf): New alias for
sprintf.
* include/freetype/internal/fttrace.h: Added Type 42 driver
component.
* src/type42/t42drivr.c: Use it.
* include/freetype/internal/internal.h (FT_INTERNAL_PCF_TYPES_H):
New macro.
