/*
Notes:
Tilemap drawing is a killer on the first level of Nost due to the whole tilemap being dirty every frame.
Sprite drawing is quite fast (See USER1 in the profiler), but requires blit-time rotation support
Sprite drawing is quite fast (See USER1 in the profiler)
Nost final boss, the priority of the arms is under the tilemaps, everything else is above. Should it be blended? i.e. Shadow.
There is an area of vid ram for linescroll, nost tests it but doesn't appear to use it.
