SET_FONT ( cFileName ) -> lValid

   Loads and activates the passed font in cFileName.
   The maximum length of cFileName is 4095 Byte. Which
   equivalents a 9x16 VGA with 256 characters ( 16x256 )

   After loadint 'SoundVis.016' SOUND & VISIONS pseudo-grafic
   functions will be activated.

   Set_Font HAS TO BE CALLED AFTER MSE_INIT() , because
   Mse_Init() sets VideoModus 3  (VGA-Color 80x25) and
   activates the ROM-CharacterSet with it !

   RETURN VALUES:

   .T. = Font is loaded
   .F. = Font isn't loaded
   ( Dos-Errors will be shown in a seperate Window )

   EXAMPLE:

      // Load Font, if .F. is returned = Error
      // ----------------------------------------
         lFont := SET_FONT('SoundVis.016')
