RAW		.EQU	$00	; BIT MASK FOR RAW FONT
;
; FONT INCLUSION CONTROLS.  THE FMT_XXX SETTING CONTROLS WHETHER THE
; FONT DATA WILL BE COMPRESSED OR NOT.  GENERALLY, COMPRESSED IS USED
; TO SAVE SPACE.  THE 6X8 FONT IS AN EXCEPTION BECAUSE IT IS USED BY
; THE TMS DRIVER WHICH RELOADS THE FONT ON-THE-FLY DURING SYSTEM
; OPERATION.  SEE TMS.ASM.
