Well, I think that you should continue this work. Certainly if
you can manage hardscrolling to work this would give much more
speedup than just unrolling the scroll loop. A long time ago
I already played around with unrolled loops and I came to the
results as Ralf estimated. Unrolling more than 8 loops didn't
further improve the performance, at least not noticable.
