Werner Lemberg	6a19a7d332	[truetype] Fix sanitizing logic for `loca' (#46223 ). * src/truetype/ttpload.c (tt_face_load_loca): A thinko caused an incorrect adjustment of the number of glyphs, most often using far too large values.	9 years ago

Werner Lemberg	58b61b6e05	[pcf] Quickly exit if font index < 0. Similar to other font formats, this commit makes the parser no longer check the whole PCF file but only the header and the TOC if we just want to get the number of available faces (and a proper recognition of the font format). * src/pcf/pcfdrivr.c (PCF_Face_Init): Updated. Exit quickly if face_index < 0. * src/pcfread.c (pcf_load_font): Add `face_index' argument. Exit quickly if face_index < 0. * src/pcf/pcf.h: Updated.	9 years ago
