The create/destroy for RenderEngine needs to happen on the same thread.

The threaded variant of RE was running the destructor on whatever
thread deleted the wrapper class and not on the thread where RE was
actually running.  This means that any GPU state that is specific
to the thread was not being correctly cleaned up.
