Subject: [PATCH] Fix clipping of content outside the bounds of the window.

https://codereview.chromium.org/899753003 incorrectly passed down the
RenderView's clipping rect all the down through transforms instead of
using the one from the LayerPaintingInfo, which is adjusted for transforms
as you recurse down the tree.
