    clutter/paint-nodes: Expose ClutterLayerNode
    
    ClutterLayerNode is a private paint node that paints the
    contents of its subnodes into an offscreen buffer, then
    paints this entire offscreen buffer at the previous draw
    framebuffer with the given opacity.
    
    It is specially interesting to the future ClutterContent
    implementation of MetaShapedTexture, for the NVidia and
    rotation cases where the contents are painted on an
    offscreen.
    
    Expose ClutterLayerNode as public API.
