* include/freetype/ftcid.h (FT_Get_CID_Is_Internally_CID_keyed, FT_Get_CID_From_Glyph_Index): New functions. * include/freetype/internal/services/svcid.h (FT_CID_GetIsInternallyCIDKeyedFunc, FT_CID_GetCIDFromGlyphIndexFunc): New function typedefs. (CID Service): Use them. * src/base/ftcid.c: Include FT_CID_H. (FT_Get_CID_Is_Internally_CID_keyed, FT_Get_CID_From_Glyph_Index): New functions. * src/cff/cffdrivr.c (cff_get_is_cid, cff_get_cid_from_glyph_index): New functions. (cff_service_cid_info): Add them. * src/cff/cffload.c (cff_font_load): Don't free `font->charset.sids' -- it is needed for access as a CID-keyed font. It gets deleted later on. * src/cid/cidriver.c (cid_get_is_cid, cid_get_cid_from_glyph_index): New functions. (cid_service_cid_info): Add them. * docs/CHANGES: Updated.
