+ This testcase ensures that we paint the background around an opaque image,
+ when the image is offset from the container via 'object-position'. This is
+ an interesting case because, by default, images fill their container,
+ which means we can often optimize away the background completely. BUT, if
+ "object-position" offsets the image from its container's content-box, we
+ can't optimize away the background; it need to be painted in the uncovered
+ area.
