Inside Macintosh merely states that "The region definition data for nonrectangular regions is stored in a compact way which allows for highly efficient access by Quickdraw procedures." and leaves it at that.

I'm afraid that Apple considers the data structures and algorithms used by Quickdraw to be trade secrets. Bill Atkinson told me he'd be glad to explain it all "when Apple let's me" but said he didn't know when that would be.
