* src/truetype/ttgload.c (TT_Load_Glyph), src/base/ftobjs.c 

(FT_Load_Glyph): "fixed" the bug that prevented embedded bitmaps from
        begin loaded when the auto-hinter is used.. This actually is a hack
        but will be enough until the internal re-design scheduled for
        FreeType 2.1

* include/freetype/cache/ftcache.h: added comments to indicate that
some of the exported functions should only be used by applications
that need to implement custom cache types
