[net.micro.amiga] Life at 20.4 generations per second

Well, I finally sat down and looked hard at how Tomas Rokicki's life
program works.  After trying many bizarre schemes to try to make it
faster, the best I could do was a minor optimization to save one
memory reference.  So now it takes 10 blits for a total of 37
operations.  If someone can make it even faster, I'd like to know,
too (certainly tell Tom).  Rather than posting the changes now, I'll
probably let the next version of blitter-life include them.

BTW, I wonder if anyone has a CAD program that attempts to do logic
decomposition.  A two-level (PLA style) optimizer is useful for
evaluating hand attempts at decomposition, but I'm curious if the
computer can do better.
