Rewrite DisplayCharacter. The new algorithm is much faster. It uses the VGA mask register to draws up to 8 pixels at once, completely getting rid of the inner loop. Pixel position / mask calculations and the check for opaque vs transparent background are moved out of the loops. The result is a single loop for the y coordinate containing an inlined __outbyte and memory write. A second loop in case of unaligned character writes.
