  * src/cff/cffdrivr.c (cff_get_glyph_name): Improve error message. (cff_get_name_index): Return if no PSNames service is available. (cff_ps_has_glyph_names): Handle CID-keyed fonts correctly. * src/cff/cfftypes.h (CFF_CharsetRec): New field `cids', used for CID-keyed fonts. This is the inverse mapping of `sids'. * src/cff/cffload.c (cff_charset_load): New argument `invert'. Initialize charset->cids if `invert' is set. (cff_font_load): In call to cff_charset_load, set `invert' to true for CID-keyed fonts. * src/cff/cffgload.c (cff_slot_load): Handle glyph index as CID and map it to the real glyph index. * docs/CHANGES: Updated.
