------- Additional Comments from Sami Kyostila <skyostil at google.com>
Thanks James. Here's a rebased patch with the following additional changes:
- Move added methods in ChromeClientImpl.h inside USE(ACCELERATED_COMPOSITING)
- LayerChromium::setMaxScrollPosition() now triggers commit
- Reset currently scrolling layer if the root layer goes away in
CCLayerTreeHostImpl::setRootLayer()

I'll follow up with more test coverage for the cases you mentioned in a
separate bug.
