    offscreen-effect: Make get_target virtual
    
    The clutter_offscreen_effect_get_target function now goes through a
    virtual method. This will be useful so that ClutterShaderEffect can
    directly return a target with the right program attached instead of
    having to modify the material returned by ClutterOffscreenEffect.
