[librsvg: 21/27] Use - use NormalizeParams

[Federico Mena Quintero <federico src gnome org>]

commit bb9400f6c000afd3437ca0a61adfd32d3537d755

    Use - use NormalizeParams
    
    It is a bit suspect that DrawingCtx::draw_from_use_node gets used from
    the Use element, and yet it has to create the NormalizeParams.
