huck:

I'm sorry I didn't describe my algorithm better the first time. Had I done so, you probably wouldn't have had to wrestle with it. I meant to describe it better, but lost track of some of the things I said vs. some of the things I meant to say. I'm sure it would've also been clearer had I not left some entries out of the %dirs hash, and had I mentioned that it's simply doing a clockwise sweep looking for the next border point.

I was also troubled by my numbering scheme, but wasn't able to come up with something cleaner. I'm certain that a bit of thinking might give a much better solution that what I currently have. But what I have is good enough for me, for now. 8^)
