If widgets want to clip things, they now need to do it themselves. By not taking care of clip, we avoid the need to track clip. And by not tracking clip, we can avoid all unnecessary cache invalidations that we were doing for render nodes whenever the clip changed. And when you are scrolling, the clip changes *a lot*.
