- * Custom Glyph Loading.

- * @description:
- * This section contains various functions used to perform so-called
- * `incremental' glyph loading. This is a mode where all glyphs loaded
- * from a given @FT_Face are provided by the client application.
- *
- * Apart from that, all other tables are loaded normally from the font
- * file. This mode is useful when FreeType is used within another
- * engine, e.g., a PostScript Imaging Processor.
- *
- * To enable this mode, you must use @FT_Open_Face, passing an
- * @FT_Parameter with the @FT_PARAM_TAG_INCREMENTAL tag and an
- * @FT_Incremental_Interface value. See the comments for
- * @FT_Incremental_InterfaceRec for an example.
