Has anyone looked at implementing the QuickDraw region algorithm in Squeak?

The patent has *certainly* run out since it has been more than 15 years
since the Mac was introduced. I'm willing to bet that QD regions are STILL
the most efficient and fastest way to describe an irregular region, and it
would likely speed up Squeak graphics by a good bit to use the algorithm as
a primitive, which is no longer covered by any patent, AFAIK.
