The steps should be as follows.

gf_load_font:
  Check whether the file in question is using the GF format.  If yes,
  load all character locators into an array, together with some other
  useful global data like `hppp' or the global bounding box.

GF_Face_Init:
  Initialize a `GF_Face' structure with the data loaded by
  `gf_load_font' and construct additional stuff like a charmap.

GF_Glyph_Load:
  Look up the character locator, load the corresponding GF glyph,
  parse it, and fill up the face's `FT_GlyphSlot' object.
