- But in the sense of rastersplit-free update, I would sugest to
- use VBeamPos() to wait for bottom of window and hope that
- blitbitmaprastport() will do it under (1 frame - windowheight).

- Somewhere in intuition there should be the physical height of screen,
- you got to add it to (window y-pos + wimdow height) to get the value
- to compare with beamcounter.
