* include/freetype/cache/ftcglyph.h, src/cache/ftcglyph.c:
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.
Fixed a dangling pointer bug in the cache code 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
* include/freetype/cache/ftcglyph.h (FTC_FAMILY_TREE): New macro.
(FTC_GCACHE_LOOKUP_CMP): Use it.
Handle reference count in `num_nodes' correctly.
* src/truetype/ttinterp.c (TT_Normalize): fixed a bug that
caused long and unecessary delays when normalizing huge vectors
* src/cache/ftcglyph.c (FTC_GNode_UnselectFamily): Use
FTC_FAMILY_FREE.
(FTC_GCache_Lookup): Handle reference count in `num_nodes' correctly.
* src/cache/ftcmanag.c (FTC_Manager_FlushN): Fixed a cache flushing
bug.
* src/truetype/ttinterp.c (Normalize): Fixed a bug that caused
long and unnecessary delays while normalizing huge vectors.
