I did my tests on 320x288x8bit.

Guys when you'll be refactoring, please don't forget to remove emulation of
that STE scrolling shifter bug in Falcon mode -- I was very surprised when
my code didn't work in STE mode but did work on real Falcon ;-) /I didn't
try Falcon mode, though. Just to be sure by some copy&paste this shifter bug
wont slip into Falcon code/
