In the current implementation of ACCELERATED_COMPOSITING, LayerSkia's are asked to redraw their contents every time the browser needs to redraw the page. This results in a lot of unnecessary drawing. Contents of these layers should only be redrawn when something changes in the layer and simply composited when its time to redraw the page.
