  1. Figure out various tiling on r200 (colorbuffer already done, texture tiling need some work)
  2. Abjust r200_blit.c to work between tiled/untiled surfaces
  3. Figure out how to upload and use hardware vertex buffer objects on r200 (and r100?)
  4. Add support for pixel_buffer_object
  5. Use some "meta" code in mesa for more acceleration (glbitmaps .... ) ...
