bitmap embolderner when the pitch of the source bitmap is
*much* larger than its width
* src/truetype/ttinterp.c: fixing aliasing-related compilation
warning
* src/truetype/ttgload.c (tt_loader_init): Re-execute the CVT
program after a change from mono to grayscaling (and vice versa).
Use correct constant for comparison to get `exec->grayscale'.
test for a valid glyph index must be deferred to the font drivers.
This patch fixes Savannah bug #18301.
* src/base/ftobjs.c (FT_Load_Glyph): Don't check `glyph_index'.

(FNT_Load_Glyph): Check validity of `glyph_index'.
src/base/ftobjs.c: fixed a bug in the automatic unpatented
hinting support which prevented normal bytecode hinting to
work properly
* src/autofit/aftypes.h: undefining AF_DEBUG to get rid of
traces
which report their English names through an Apple Roman
(platform,encoding) pair, with language_id != English
if the font uses another name entry with language_id == English,
it will be selected correctly though.
* src/truetype/ttobjs.c: add unpatent-hinting selection for
"mingli.ttf"
values which have the upper two bytes set to 0xFF instead of 0xFF
(as it happens in at least two CJKV fonts, `HAN NOM A.ttf' and
`HAN NOM B.ttf').
* src/smooth/ftgrays.c [GRAYS_USE_GAMMA]: Really remove all code.

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%.

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.

solved compiler warnings as well as C++ compilation problems

adding a new API named FT_Get_TrueType_Engine_Type to determine
wether we have a patented, unpatented or unimplemented TrueType
bytecode interpreter.
the FT_Get_Module_Flags API was removed consequently.

(T1_Face_Init), src/type42/t42objs.c (T42_Face_Init): Update.

`loadSize' and `loadStack'.

* src/cff/cffobjs.h (cff_size_select), src/sfnt/sfdriver.c
(sfnt_interface), src/truetype/ttdriver.c (tt_size_request): Fix
compiler errors/warnings when TT_CONFIG_OPTION_EMBEDDED_BITMAPS is not
defined.
* src/sfnt/ttmtx.c (tt_face_load_hmtx, tt_face_get_metrics): Fix
possible segment faults for the non-FT_OPTIMIZE_MEMORY'ed versions.
(finally!)
For most OpenType tables, `tt_face_load_xxxx' simply loads the table
and `face->root' is set later in `sfnt_load_face'. Here, we try to
make this work for _all_ tables.
* src/sfnt/ttsbit.c, src/sfnt/ttsbit0.c, src/sfnt/ttload.c,
src/sfnt/ttmtx.c: all `tt_face_load_xxxx' should load the table and
then exit. Error handling or setting face->root is done later in
`sfnt_load_face'.
Pretty trace messages.
* src/sfnt/sfobjs.c (sfnt_load_face): Work harder.
Mac bitmap-only fonts are not scalable.
Check that `face->header.Units_Per_EM' is not zero.
(LOAD_, LOADM_): Pretty trace messages.
* src/sfnt/ttsbit0.c (tt_face_load_strike_metrics): Read metrics from
`eblc'.
* src/sfnt/ttcmap.c (tt_face_build_cmaps), src/sfnt/ttpost.c

face->max_profile.numGlyphs, instead of face->root.num_glyphs.

Check table length in non-FT_OPTIMIZE_MEMORY'ed `tt_face_load_hmtx'.
* src/sfnt/sfobjs.c (sfnt_load_face): Take care of missing metrics
tables. The last change makes Mac bitmap-only font not load and this
fixes it.
* src/truetype/ttgload.c (load_truetype_glyph): Fix compilation error
when FT_CONFIG_OPTION_INCREMENTAL is defined.
