Jeck - Please review: this makes minor changes to a lot of files, and major changes to the WCache flatten() function.

* Removed all calls to Release(JQuad*).
* Updated flatten(). Prior flatten was buggy beyond belief.
* Done some extensive testing, but if this causes more trouble than it fixes, we'll have to revert. It's too close to release time.
