Layer painting from Compositing
For display list based invalidation, we need to know the widget area to invalidate (generated from display list construction, layer construction, and ThebesLayer painting) before we trigger a widget paint event. We need to split layer transactions into a Validate() phase that draws all thebes layer contents, and then a separate Composite() phase. This is similar to what Shadow layers are doing ready. D3D10 layers already supports Validate() properly, the other backends could probably use better implementations that what I have here.
