Some fixes for saved surfaces
- If we have a saved surface, and app relayouts to visible before we
started entry animation, we need to restore the saved surfaces.
Otherwise the surface might get stuck in the saved state, because
we may not get to run any animation after this relayout.
- Keep track of the allDrawn while we're using the saved surfaces,
so that we can rely on allDrawn itself, instead of whether we're
using saved surfaces.
- If the app is set to visible when it's exiting, clear the exiting
flags. Also, save the surface if we cancel an exiting animation.
- More debug logging.
