Groking the 3D canvas. I got collisions working somewhat, but now I'm stuck on some other aspects of the system.

I've put the third-person body on hold for now, since the proof-of-concept for it has demonstrated workability.

Currently working on: being able to manage compute resources across web pages / urls. The user should be able to navigate between web3 and web2 pages seamlessly. I'm anticipating memory leaks and other performance issues, necessitating robust memory management like in the old days.
