Georges Basile Stavracas Neto ea20076bad clutter/offscreen-effect: Implement paint_node()
The paint node tree that ClutterOffscreenEffect generates is
simple:

  Root
    |------------+
    |            |
  Layer        Pipeline
    |
  Actor

Right now, both pre-paint and ClutterLayerNode push the offscreen
to the framebuffer stack. That's harmless, and will go away soon
anyway.

The actor node is created and added in a separate function because
it'll be reused by the next commit.
