     The _unregisterfonts function frees memory previously allocated
     and used by the _registerfonts function. The _unregisterfonts
     function removes the header information for all fonts and unloads
     the currently selected font data from memory.
 
     Any attempt to use the _setfont function or the _outgtext function
     after calling _unregisterfonts results in an error.
 
     Return Value
 
     None.
