  [cff] Better tracing of the parsing process. * src/cff/cffload.c (cff_subfont_load, cff_font_load): Decorate with FT_TRACE. * src/cff/cffparse.c (cff_parse_font_matrix, cff_parse_font_bbox, cff_parse_private_dict, cff_parse_cid_ros): Updated. (CFF_FIELD_NUM, CFF_FIELD_FIXED, CFF_FIELD_FIXED_1000, CFF_FIELD_STRING, CFF_FIELD_BOOL, CFF_FIELD_CALLBACK, CFF_FIELD, CFF_FIELD_DELTA): Add argument for ID. (cff_parser_run): Decorate with FT_TRACE. * src/cff/cffparse.h (CFF_Field_Handler) [FT_DEBUG_LEVEL_TRACE]: Add `id' member. * src/cff/cfftoken.h: Add IDs to all fields.
