    shadow-factory: Receive CoglFramebuffer
    
    Following up last commit, this commit adds a CoglFramebuffer
    argument to meta_shadow_paint(), and stops using the draw
    framebuffer internally.
    
    The only consumer of this API, MetaWindowActor, still passes
    the draw framebuffer though.
