------- Additional Comments from Simon Fraser (smfr) <simon.fraser at apple.com>
On Mac, redrawing of composited iframes on scrolling happens via the swizzled
setNeedsDisplayInRect: method in WebTMLView.mm. It is broken on Windows and in
WebKit2, so something like this patch is needed.

However, this patch adds an invalidate for every scroll, not just scrolls of
iframes in compositing layers. We certainly don't want that.
