Register a scene with the engine. Builds deferred work, sorts renderables by order,
and adds the scene to its bound surface's render list. A scene clears its target unless
it was created with createOverlayScene, in which case it composites over its base scene
and is kept immediately after it. The scene is always attached to scene.surface
(which equals the engine itself in the single-canvas case).
