+
+ Say you have `(Foo*)x' and want to assign, pass, or return it as
+ `(Bar*)'. If you simply say `x' or `(Bar*)x', then the C compiler
+ would warn you that type casting incompatible pointer types breaks
+ strict-aliasing. The solution is to cast to `(void*)' instead which
+ is the generic pointer type, so the compiler knows that it should
+ make no strict-aliasing assumption on `x'. But the problem with
+ `(void*)x' is that seems like in C++, unlike C, `void*' is not a
+ generic pointer type and assigning `void*' to `Bar*' without a cast
+ causes an error. The solution is to cast to `Bar*' too, with
+ `(Bar*)(void*)x' as the result -- this is what the patch does.
+
+ * include/freetype/cache/ftccache.h (FTC_CACHE_LOOKUP_CMP),

+ FT_MEM_REALLOC, FT_MEM_QALLOC, FT_MEM_QREALLOC, FT_MEM_FREE),

+ to not break strict aliasing.
+
+ * src/base/ftinit.c (FT_USE_MODULE): Fix wrong type information.
+
+ * builds/unix/configure.ac (XX_CFLAGS): Remove -fno-strict-aliasing.
+
+2005-05-23 David Turner <dturner@freetype.org>

+
+2005-02-25 David Turner <david@freetype.org>
+
+ Implement several memory optimizations to drastically reduce the
+ heap usage of FreeType, especially in the case of memory-mapped
+ files. The idea is to avoid loading and decoding tables in the
+ heap, and instead access the raw data whenever possible (i.e., when
+ it doesn't compromise performance).
+
+ This has several benefits: For example, opening vera.ttf now uses
+ just a small amount of memory (even when the FT_Library footprint is
+ accounted for), until you start loading glyphs. Even then, you save
+ at least 20KB compared to the non-optimized case. Performance of
+ various operations, including open and close, has also been
+ dramatically improved.
+
+ More optimizations to come, especially for the auto-hinter.
+
+ * include/freetype/internal/sfnt.h (TT_Face_GetKerningFunc): New
+ function type.
+ (SFNT_Interface): Add it.

+ TT_Kern0_PairRec): Don't define if FT_OPTIMIZE_MEMORY is set.
+ (TT_FaceRec): Define `horz_metrics', `horz_metrics_size',
+ `vert_metrics', `vert_metrics_size', `hdmx_table',
+ `hdmx_table_size', `hdmx_record_count', `hdmx_record_size',
+ `hdmx_record_sizes', `kern_table', `kern_table_size,
+ `num_kern_tables', `kern_avail_bits', `kern_order_bits' if
+ FT_OPTIMIZE_MEMORY is set.
+ Don't define `hdmx', `num_kern_pairs', `kern_table_index',
+ `kern_pairs' if FT_OPTIMIZE_MEMORY is set.
+
+ * src/base/ftdbgmem.c (ft_mem_table_set): Don't shadow variable.

+ taken from `ttload.c' and `ttload.h'.

+ `tt_face_get_kerning', and `tt_face_done_kern' for
+ FT_OPTIMIZE_MEMORY.
