ALLEGRO_FONT - Allegro 5 API

       A  handle  identifying  any  kind  of  font.  Usually you will create it with al_load_font(3alleg5) which
       supports loading all kinds of TrueType fonts supported by the FreeType library.  If you instead pass  the
       filename  of a bitmap file, it will be loaded with al_load_bitmap(3alleg5) and a font in Allegro’s bitmap
       font format will be created from it with al_grab_font_from_bitmap(3alleg5).
