Fixed cutout not drawn when it's inside rounded corner rect

We may clear the color(if useInvertedAlphaColor is true) of the rounded
corner rects before drawing rounded corners. If a cutout happens to be
inside one of there rects, it will be cleared, so we should draw rounded
corners before cutout.
