* src/cff/cffdrivr.c (cff_get_glyph_name): Improve error message.

Browse Source 
(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.

rounded, making them virtually unusable if not loaded with
FT_LOAD_LINEAR_DESIGN.
- Indexing CID-keyed CFF fonts is now working: The glyph index is
correctly treated as a CID, similar to FreeType's CID driver
module. Note that CID CMaps support is still missing.
II. IMPORTANT CHANGES
