Subject: [PATCH]         * 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
