Ok, the first revision (r52) of Box2DAS3 for the next version is available now on SVN. Phew, that was a lot of work.

Lots of stuff doesn't work, but the reduced testbed ought to compile and run.

Quick bulletin that I'm working on porting Erin's recent changes to Box2D, which will eventually become the bulk of 2.1. It's a pretty big job, which I'm doing at once, so there'll be nothing compilable for a while. I've done maybe 10%.

I have a few changes planned for 2.1 beyond mirroring the C++. Box2DFlashAS3 will be breaking compatibility with the C++ and backwards compatibility in both API and implementation.
