There's a new scroll layer now maintained by the common RenderLayerCompositor which applies the scrolling transform. The additional transform added by the LayerRendererChromium should now be removed.

Created attachment 68255 [details] proposed patch updateLayersRecursive is (incorrectly) also called by LayerRendererChromium::prepareToDrawLayers() but the invocation in drawLayers() is the one that really matters. I'll clean up the prepareToDrawLayers() in a separate CL.
