/* */
/* get_kerning :: A function handle to return the unscaled */
/* kerning for a given pair of glyphs. Can be */
/* set to 0 if the format doesn't support */
/* kerning. */
/* */
/* attach_file :: This function handle is used to read */
/* additional data for a face from another */
/* file/stream. For example, this can be used to */
/* add data from AFM or PFM files on a Type 1 */
/* face, or a CIDMap on a CID-keyed face. */
/* */
/* get_advances :: A function handle used to return advance */
/* widths of `count' glyphs (in font units), */
/* starting at `first'. The `vertical' flag must */
/* be set to get vertical advance heights. The */
/* `advances' buffer is caller-allocated. */
/* Currently not implemented. The idea of this */
/* function is to be able to perform */
/* device-independent text layout without loading */
/* a single glyph image. */
/* */
/* request_size :: A handle to a function used to request the new */
/* character size. Can be set to 0 if the */
/* scaling done in the base layer suffices. */
/* */
/* select_size :: A handle to a function used to select a new */
/* fixed size. It is used only if */
/* @FT_FACE_FLAG_FIXED_SIZES is set. Can be set */
/* to 0 if the scaling done in the base layer */
/* suffices. */
/* <Note> */
/* Most function pointers, with the exception of `load_glyph' and */
/* `get_char_index' can be set to 0 to indicate a default behaviour. */
