    st-private: Receive a CoglFramebuffer
    
    Same case of the previous patch; _st_paint_shadow_with_opacity()
    uses cogl_get_draw_framebuffer(), and this patch makes it receive
    a CoglFramebuffer as a parameter instead.
    
    The cautious reader might notice that this commit apparently goes
    against the long-term goal, for it introduces more instances of
    cogl_get_draw_framebuffer(). This is not wrong, but these introduced
    ones will be removed later on, when ClutterActor.paint() receives
    a CoglFramebuffer as a parameter instead.
