src/type42/t42parse.c, src/winfonts/winfnt.c: hardening the code
against out-of-bounds conditions when allocating arrays. This is
for the cases where FT_NEW_ARRAY and FT_RENEW_ARRAY are not used
already. Introducing the new FT_ALLOC_MULT and FT_REALLOC_MULT
macros.
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.

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.

default location.

with...
(FTMODULE_H_INIT, FTMODULE_H_CREATE, FTMODULE_H_DONE): New
variables. Reason for the change is that it is not possible to have
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.

* include/freetype/freetype.h (FT_FaceRec): Mention that fields may be
changed after file attachment.

the internal headers, and removes existing ones if finds in the
target install directory
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...

were part of FT_Select_Size/FT_Request_Size and are made independent
functions so that metrics are not set again and again.
* src/base/ftobjs.c (FT_Select_Size, FT_Request_Size): Metrics are set
only when driver's size_select/size_request is NULL. That is, drivers
should set the metrics themselves.

does cause some problems without rounding.

(tt_face_load_sbit_strikes, tt_face_load_strike_metrics): The
advertised metrics in `available_sizes' are different from those
actually used.
src/autofit/aftypes.h, src/autofit/afloader.c, src/autofit/autofit.c:
adding experimental implementation of "warp hinting" (new hinting
algorithm for gray-level and LCD rendering). It is disabled by default,
you need to #define AF_USE_WARPER in aftypes.h to enable it.

* src/psaux/psconv.c, src/psaux/psconv.h: New files to provide
conversion functions (e.g, PS real number => FT_Fixed) for the

formattings in vertical metrics faking. There are still rooms for
improvements (and so do the CFF module).

the linear advance fields as they are only for the outline glyphs.

The meaning of FT_LOAD_FORCE_AUTOHINT is changed so that no real
change need be made to the code.

decide whether to use the auto-hinter according to documentation.
There should to be no real difference.
Some checks (e.g., is text height positve?) after the glyph is loaded.

src/sfnt/ttbdf.h, src/sfnt/ttbdf.c, src/sfnt/sfobjs.c:
Added support for an embedded 'BDF ' table within SFNT-based
bitmap font files. This is used to store atoms & properties from
the original BDF fonts that were used to generate the font file.
the feature is controled by TT_CONFIG_OPTION_BDF within 'ftoption.h'
and is used to implement FT_Get_BDF_Property for these font files.
At the moment, this is still experimental, the BDF table format isn't
cast into stone yet.
implementation of the LIGHT hinting mode to completely disable
horizontal hinting. This is an experimental effort to integrate
David Chester's latest patch without fucking the other hinting
modes as well.
Note that this doesn't force auto-hinting for all fonts however.
for cmap format 4. For overlapped but sorted segments, which is
previously considered unsorted, we still use binary search.
* src/sfnt/ttcmap.h (struct TT_CMapRec_): Replace `unsorted' by
`flags'.
(TT_CMAP_FLAG_UNSORTED, TT_CMAP_FLAG_OVERLAPPED): New macros.
* src/sfnt/ttcmap.c (OPT_CMAP4): Removed as it is always defined.
(struct TT_CMap4Rec_): Remove `old_charcode' and `table_length'.
(tt_cmap4_reset): Removed.
(tt_cmap4_init): Updated accordingly.
(tt_cmap4_next): Updated accordingly.
Take care of overlapped segments.
(tt_cmap4_validate): Make sure the subtable is large enough.
Do not check glyph_ids because some fonts set the length wrongly.
Also, when all segments have offset 0, glyph_ids is always invalid. It
does not cause any problem so far only because the check misses
equality.
Distinguish between unsorted and overlapped segments.
(tt_cmap4_char_map_linear, tt_cmap4_char_map_binary): New functions to
do "charcode => glyph index" by linear/binary search.
(tt_cmap4_char_index, tt_cmap4_char_next): Use
tt_cmap4_char_map_linear and tt_cmap4_char_map_binary.
(tt_face_build_cmaps): Treat the return value of validator as flags
for cmap.
tt_cmap12_next): New struct/function for fast "next char".
(tt_cmap12_char_map_binary): New function to do "charcode => glyph
index" by binary search.
(tt_cmap12_char_index, tt_cmap12_char_next): Use
tt_cmap12_char_map_binary.
(tt_face_build_cmaps): Check table and offset correctly (equality is
missing).
* builds/amiga/smakefile: Adjusted the compiler options
to the current sources, now really builds the gxvalid, gzip
and psnames modules.
* builds/amiga/src/base/ftsystem.c: The assumed Seek() position
in the file cache was off by one byte which could cause false
errors in font files.

tt_face_load_sfnt_header to tt_face_load_directory.

(sfnt_init): New function to fill in face->ttc_header. A non-TTC font
is synthesized into a TTC font with one offset table.
(tt_face_load_sfnt_header): Use sfnt_init.
Fix an invalid access when the font is TTC and face_index is -1.
