Update compositing/RTL tests to fail if the root layer is shifted incorrectly
Created attachment 140577 [details] Patch
I guess I wasn't clear on how I fixed it, so here's a better change description: I set margin:0 on all tests, set the background to red, and then added a big white layer over top of the entire root layer. If the root layer is incorrectly shifted in the compositor, then it won't cover the red background and the test will fail. This will probably only fail on Chromium, because we logically end up doing a clear with the root background color.
