HEAD

   Optimize character rendering in 32bpp mode, with unrolled rows and
   pairwise foreground / background pixel rendering.

   This does double-pixel rendering for the common font widths (8, 12,
   16, and 32 pixels wide), resulting in a significant speed-up.

   No regression noticed on 32-bit architectures.

   Tested by weerd@, and by abieber@ on macppc.

   From John Carmack, thanks!
