On Android we have until now determined the compositor widget's size by querying the values from the ANativeWindow. However, since bug 1780093 landed we can now switch between which Surface we are rendering in to, and as a result we appear to be using the wrong size some of the time. This patch is a speculative attempt to fix this, by using the size passed to ResumeAndResize() (which itself comes from the Surface's surfaceChanged() callback) rather than querying the window.
