Summary Make use of geometry information to decide which layers become composited

The current RenderLayerCompositor algorithm only makes use of painting order trees when deciding which layers should be composited. This means that an element like <video> can kick a bunch of non-overlapping elements into compositing layers, with resulting impact on text antialiasing. We can improve the RenderLayerCompositor algorithm to look at overlap.
