-   *    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.
