matt kuhlenschmidt 641bb5abdf Slate Global Invalidation System ...

This change makes it possible to remove the layout and painting overhead that Slate performs every frame.  The system is off by default as we continue to iterate on it.

However, this includes massive changes to batching, rendering, hit testing, and invalidation panels which are permanent changes and cannot be disabled.
