- * Type 2 CIDFonts implementation
- *
- * For Type 2, the CIDFont program is actually a TrueType font program, which has
- * no native notion of CIDs. In a TrueType font program, glyph descriptions are
- * identified by glyph index values. Glyph indices are internal to the font and are not
- * defined consistently from one font to another. Instead, a TrueType font program
- * contains a 'cmap' table that provides mappings directly from character codes to
- * glyph indices for one or more predefined encodings.
