[iOS WebKit2] Partial repaint is broken
https://bugs.webkit.org/show_bug.cgi?id=131056
Reviewed by Dean Jackson.
* Shared/mac/RemoteLayerBackingStore.mm:
(WebKit::RemoteLayerBackingStore::display):
We need to check if the repaint rects themselves cover the whole
layer's surface, not just their bounds. Otherwise, we'll optimize
out the back->front copy and end up not painting the whole layer.
