Simple ChangeLog update:
2004-06-23 David Turner <[email protected]>
* include/freetype/internal/ftmemory.h, src/base/ftutil.c,
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
appropriate to slightly improve performance.
