| This tests checks that deferred compositing is still invoked when nothing except touch hit rects change. |
| The trickiness is that touch hit rects cannot be recomputed until after compositing is updated, so |
| there is a risk of accidentally skipping updating touch rects unless we ping the compositor correctly. |
