+ * src/sfnt/sfobjs.c (sfnt_open_font): Allow 'typ1' version
+ tag in the beginning of sfnt container.
+ * src/sfnt/ttload.c (check_table_dir): Return
+ `SFNT_Err_Table_Missing' when sfnt table directory structure
+ is correct but essential tables for TrueType fonts (`head',
+ `bhed' or `SING') are missing. Other errors are returned
+ by SFNT_Err_Unknown_File_Format.
+
+ * src/base/ftobjs.c (FT_Open_Face): When TrueType driver returns
+ `FT_Err_Table_Missing', try `open_face_PS_from_sfnt_stream'.
+ It is enabled only when old mac font support is configured.
