SCROLL.PRG - Bending and disting scroll.

This scroll has a random startup that chooses between two different scrolls. A normal dist-bending scroll and a norge scroller. Norge is Norway in swedish. The reason for this name is that I invented and coded it on a convention in Norway 2 years ago.

I used to be proud of this scroll but it is getting pretty old. Original code is 3 years old. It has been much improved since then but the last 2.5 years it hasent happened too much with it except better clearing routine.

This scroll uses a technique that I call rotating buffers which saves lot of memory compared to double buffers.
