To Do:

- Raster effects (level 5 interrupt is used for that). In pbancho
  they involve changing the *vertical* scroll value of the layers
  each scanline (when you are about to die, in the solo game).
  In gogomile they weave the water backgrounds and do some
  parallactic scrolling on later levels. *partly done, could do with
  some tweaking

- The scroll values are generally wrong when flip screen is on and rasters are often incorrect
