    clutter/paint-node: Expose clutter_paint_node_get_framebuffer()
    
    Mutter needs to know which framebuffer the paint nodes will be
    drawn into, and using cogl_get_draw_framebuffer() directly is
    not an option since ClutterRootNode only pushes the draw fb
    at draw time.
    
    Expose clutter_paint_node_get_framebuffer().
