Layers Anyone??
That is THE problem with the Amiga, getting maximum performance. You can do
anything with the built-in routines, which is wonderful, but there isn't enough
documentation to do things efficiently.
If I were you (and had the time), I would write a routine that writes
directly to the bitmap, and code my own clipping routines. I'm going to do at
least the former when I have time, like perhaps next year. Good luck! —Mike
