Description Vangelis Kokkevis 2010-09-21 09:42:54 PDT 
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.

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.
