Simple ChangeLog update: 

2004-06-23  David Turner   <david@freetype.org>

        * 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.
