* include/freetype/internal/ftobjs.h, src/base/ftobjs.c, src/bdf/bdfdrivr.c,
src/pcf/pcfdriver.c, src/pfr/pfrsbit.c, src/sfnt/ttsbit.c,
src/type42/t42objs.c, src/winfonts/winfnt.c: introduced three new functions
to deal with glyph bitmaps within FT_GlyphSlot objects. these are:
ft_glyphslot_free_bitmap
ft_glyphslot_alloc_bitmap
ft_glyphslot_set_bitmap
these are much more convenient to use than managing the FT_GLYPH_OWN_BITMAP
flag manually. the font drivers have been modified to use them as well.
* src/cache/ftlru.c: fixed an invalid assertion check
to control memory debugging with FreeType. See the description of
"FT2_DEBUG_MEMORY", "FT2_ALLOC_TOTAL_MAX" and "FT2_ALLOC_COUNT_MAX"
in DEBUG.TXT
* src/cache/ftccache.c, src/cache/ftccmap.c, src/cache/ftcsbits.c,
ftlru.c: fixed the cache sub-system to correctly deal with out-of-memory
conditions.
* src/pfr/pfrobjs.c, src/pfr/pfrsbits.c: fixing compiler warnings and a
small memory leak
* src/psaux/psobjs.c (t1_reallocate_table): fixed a bug (memory leak) that
only happened when trying to resize an array would end in an OOM.
* src/smooth/ftgrays.c: removed compiler warnings / volatile bug
* src/truetype/ttobjs.c: removed segmentation fault that happened in
tight memory environments.
* src/base/ftdebug.c (ft_debug_init), builds/win32/ftdebug.c
(ft_debug_init), builds/amiga/src/ftdebug.c (ft_debug_init): changed the
syntax of the FT2_DEBUG environment variable used to control debugging
output (i.e. logging and error messages). It must now look like:
any:6 memory:4 io:3 or
any:6,memory:4,io:3 or
any:6;memory:4;io:3
