Ensure we change SurfaceView size from UI thread.

We need to change the SurfaceView size from the UI thread
so that we can appropriately deliver the SurfaceChanged
callback. We also need to not preserve geometry
in this case, as if we don't update the surface
and layout size together we could get scaling. This still has
some potential for holes, as transactions are not synced with
the parent renderer, but we have other methods to avoid
these in the case of resizing. This fixes the remaining
issues with content sizing and surface view "out of sync".
