/* There are a large number of possible ways to implement bitmap on
 * this hardware, most of them have some sort of drawback.  Here are a
 * few that spring to mind:
 * 
 * Blit:
 *    - XY_MONO_SRC_BLT_CMD
 *         - use XY_SETUP_CLIP_BLT for cliprect clipping.
 *    - XY_TEXT_BLT
 *    - XY_TEXT_IMMEDIATE_BLT
 *         - blit per cliprect, subject to maximum immediate data size.
 *    - XY_COLOR_BLT 
 *         - per pixel or run of pixels
 *    - XY_PIXEL_BLT
 *         - good for sparse bitmaps
 *
 * 3D engine:
 *    - Point per pixel
 *    - Translate bitmap to an alpha texture and render as a quad
 *    - Chop bitmap up into 32x32 squares and render w/polygon stipple.
