Summary [chromium] LayerRendererChromium::prepareToDrawLayers logic needs cleanup

There are a couple of issues here: 1. When the window size changes the entire root layer texture must be updated. There's no reason to perform scrolling operations there. 2. When the scroll offset is larger than the size of the page we shouldn't be doing the glCopyPixels as there's no useful pixels to copy from 3. It shouldn't call updateLayersRecursive as that method is actually called right before the layers are drawn in the drawLayers() method.
