The patent expired long ago, but the algorithm was designed to allow overlapping windows to work on the original Mac, and was quite speedy. It was only superseded by specialized hardware many years later, but still has potential uses even though no-one bothers to.

How would that compare to Morphic's clipped top-down drawing, which already is quite a bit more efficient than the usual bottom-up drawing?
