-
- I got a solution for this already. ScreenToFront() and
- ScreenToBack() are the solutions. I wonder if double/triple
- buffering could be done with these..

-
- Oh yes .. I forgot that if chunky2planar is used, native
- planar bitmaps are present and sprites, too.
-
- On OCS/ECS sprite masking cant be used though.

- This was PS3M in fact .. funny that SetIntVector() does
- not enable the interrupt I set with it. Well, it is
- more low-level than AddIntServer() though.
- An interrupt setted with SetIntVector() is like HW interrupt,
- it ends to rte and it must write to intreq+custom also.
