Better "filled iso" drawing in 3D
Custom range on "filled iso" 3D views produces ugly plots, where one sees inside the cut elements. (In the meantime, one can use Plugin(CutMap) with "ExtractVolume" set to 1 (or -1): this will generate a new view with an actual "cut" on the front (an "iso-volume"). Then one could use Plugin(Skin) to extract the outer surface.)
