Commit 84ad2a2205216f540b89bbd2986472d37a82f801
2001-03-16T15:03:13
Added function get_cff_glyph_name() in order to facilitate getting a glyph name for glyph index via FT_Get_Glyph_Name(). In function cff_get_interface(), added support for getting a glyph name via the "glyph_name" module interface (used in the function FT_Get_Glyph_Name()). We use the new function get_cff_glyph_name().
