Well, if an object is at the very right (127) side, it must already have
15 Pixels blanked out. The position where the ANDing must start is at
127-15 = 112, since, as I was trying to explain, I can't move anything
past position 127 (or before pos 0). So I'm gonna lose 15 Pixels on each
side. Standing on position 127 (0) and getting the ship smoothly out of
the screen without losing any width would require shifting of the shape
data.
Or are we talking something totally different here? :-)

Please allow up to three days to deliver :-)

Hehe, if I'd understand why, there was no problem to solve :-)

Maybe I get it done today, but I fear it'll be wednesday night until I
find some minutes.
