Compound Boolean Geometry

Well, converting from simple boolean geometry code to Compound boolean geometry code wasn't quite as simple as I first thought. BUT, it wasn't too bad either. Basically, you just have to do the same inside/outside/shared/unshared tagging that you do with simple paths, and apply it to all subpaths as well. There's some fiddly bits about making sure you are inside an odd number of the opposite path set's paths, but it wasn't too bad. The result is shown below:

You are so clever! It really is a joy to see how you puzzle out problems. I'm glad to call you my friend. :)

OT: I need some idea of what you'd want on a hat. I'll send a replacement one for tugrik some time this year, and it makes sense to add one for you to the fedex package (vs. sending one separately or handing off at FC). Designs are limited to something I can do in about 10 rows or less of Fair Isle (say 20x10 repeating pattern with a few other constraints), so simpler is better. Default is a sprite of your avatar. Colour suggestions would also be a plus.

O.K. I understand what you're doing. We didn't give it that name when we used it in Descriptive Geometry. And I certainly couldn't program a system to do it.
