Should get the internal display root window rather than the primary, and
generalize this to a helper method for setting rotation.

That being said, I'd prefer we find what is animating on a display update and
stop it from doing so. Since this seems to only happen in touchview I suspect,
directly or indirectly, that it's MaximizeModeWindowManager.
