Hardware tricks:
- panning (large virtual screen, scrolling + copy at bottom/top)
- y-wrap (split-screen, used by amifb)
And then there's the question whether copying rectangles is faster than just
redrawing the affected area. On some hardware it is, on other it isn't.
Many years ago we also had `copcon', the Amiga Copper console, but that project
died. It was quite interesting though, since it allowed to split the screen on
every character line and reorder the lines without redrawing.
