destroy_font - Frees the memory being used by a font structure. Allegro game programming library.

       Frees the memory being used by a font structure. Don't use this on the default global Allegro font or any
       text  routines using it could crash. You should use this only on fonts you have loaded manually after you
       are done with them, to prevent memory leaks in your program.
