Patch for review/discussion.  This is a larger patch than I would prefer (108kb), but since it changes interfaces and ownership models it's very difficult to break up into independent pieces.

The intended use of SharedContext3D is that callers can use it as if it were a GraphicsContext3D, being careful to re-bind everything they need on every draw, and that SharedContext3D would have caching to avoid issuing redundant calls to the underlying GraphicsContext3D.  I've left the caching out of this patch as it was already getting pretty big.
