    GTK/GL: Draw pretty translucent polygons in thindraw-poly mode
    
    Eventually we need some way to configure this.. it might be nice in
    non-thindraw mode too. If people want thin-draw to gain extra speed,
    rather than have it actually slower (due to fill + outline), then a
    way to turn it off would also be useful.
