(CFLAGS), builds/compiler/gcc.mk (CFLAGS): Remove
-fno-strict-aliasing.
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),
include/freetype/cache/ftcmru.h (FTC_MRULIST_LOOKUP_CMP): Remove

we're dealing with a BDF font (the old code allocated 64 Kb right
before any test).

the LZW header before doing anything else. This helps avoid un-necessary
heap allocations (400 Kb of heap memory for the LZW decoder ! Oh my !)

though the code savings is smaller.
Fix serious typo which prevented correct TT rendering.

various bug-fixes and drastic heap usage reduction improvements.
* include/freetype/config/ftmodule.h: the auto-fitter is now the
only supported auto-hinting module
* include/freetype/config/ftstdlib.h: adding FT_INT_MAX definition
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 had several impacts: first, opening vera.ttf uses a ridiculous amount
of memory (when the FT_Library footprint is accounted for), until you start
loading glyphs. Even then, you'll save at least 20 Kb compared to the non
optimized case. performance of various operations, including open/close
has also been dramatically improved.
More optimisations to come. The auto-hinter eats memory like crazy? This
must be stopped...
src/truetype/ttpload.c, src/truetype/ttpload.h, src/truetype/ttgload.c:
added the temporary configuration FT_OPTIMIZE_MEMORY to control various
optimizations used to reduce the heap footprint of memory-mapped TrueType
files.
* src/truetype/ttpload.c (tt_face_load_loca, tt_face_get_location,
tt_face_done_loca): when FT_OPTIMIZE_MEMORY is set, the locations table
is read directly from memory-mapped streams, instead of being decoded
into the heap.
* src/truetype/ttpload.c: only load the CVT and fpgm tables when the
bytecode interpreter is compiled in.
in the memory debugger. Also a new function FT_DumpMemory() was added.
It is only available in builds with FT_DEBUG_MEMORY defined, and you
must declare it in your own code to use it, i.e. with something
like:
extern void FT_DumpMemory( FT_Memory );
...
FT_DumpMemory( memory );

src/base/ftmemdbg.c: introducing the new FT_QAlloc and FT_QRealloc
functions that do perform allocation without zero-ing out the
corresponding blocks. Corresponding macros like FT_QALLOC, FT_QNEW,
etc.. have been defined too
* include/freetype/config/ftmodule.h: changed the order of modules
in order to _dramatically_ improve the performance of face open/close
operations. For example, putting the TrueType driver first in the
list results in a 5X speedup when opening Vera.ttf !!
The problem is really that the PCF and/or BDF drivers are broken
and do a lot more than necessary simply to detect that they
cannot handle the font file.
* src/sfnt/ttload.c: small optimization in the kerning table
verifier, speeds up TrueType face opening by about 7%.
Also changed code to use the new FT_QNEW_ARRAY call when

* src/sfnt/sfobjs.c: removing compiler warning
Improve inter-letter spacing for autohinted glyphs.
* include/freetype/freetype.h (FT_Glyph_Metrics): Add elements
