    themingengine: change coordinates for _gtk_theming_engine_paint_spinner
    
    Instead of assuming the current point is the center of the spinner and
    rotating around it, make it behave like gtk_render_icon(), i.e. the
    current point is at the top-left corner of the desired spinner square.
    
    This is needed for subsequent commits that add blur support to spinner
    shadows.
