[Webkit-unassigned] [Bug 178396] Composited frames incorrectly get requestAnimationFrame throttled

--- Comment #3 from Simon Fraser (smfr) <simon.fraser at apple.com> ---
RenderLayer::childrenClipRect() takes the document rect (renderer().view().unscaledDocumentRect()) and calls localToAbsoluteQuad() on it, which maps it through the scroll offset, so it can end up with some large negative offset.

This seems wrong; we should probably map LayoutRect::infiniteRect() through and then clip to the document rect.
