Ensure SurfaceView requests WM relayout when size changes.
In the case of scaled SurfaceViews with a fixed size.
It is possible for the surface layout size to change
without a change to the surface size or position. In this
case we need to inform the window manager so it can update
frames and scaling. This has presented in Camera and required
workarounds such as changing the fixed surface size to trigger
an update (leading to visual artifacts).
