al_init_font_addon - Allegro 5 API

       Initialise the font addon.

       Note  that  if  you  intend  to  load  bitmap fonts, you will need to initialise allegro_image separately
       (unless you are using another library to load images).

       Similarly, if you wish to load truetype-fonts, do not forget to also call al_init_ttf_addon(3alleg5).

       Returns true on success, false on failure.  On the 5.0 branch, this function has no  return  value.   You
       may  wish  to  avoid  checking  the  return  value  if your code needs to be compatible with Allegro 5.0.
       Currently, the function will never return false.
