    clutter/paint-node: Expose clutter_paint_node_paint()
    
    When painting to an offscreen framebuffer, MetaShapedTexture will
    need to have full control of the painting routines of paint nodes.
    As such, expose clutter_paint_node_paint() to allow forcing a
    paint nodes paint from MetaShapedTexture.
