Vlad Zahorodnii 6d0cca5c7f Move all dirty region scene repaint scheduling to Scene
The Compositor contains nothing that can potentially get dirty and need
repainting.

As is, the advantages of this move aren't really noticeable, but it
makes sense with multiple scenes.

Backend parts are far from ideal, they can be improved later on as we
progress with the scene redesign.
