Yes, to avoid coincident surfaces. There may be a small amount of
interreflection this way, but I can't detect it. This model is not the main
subject of the image it was intended for so I didn't try too hard.

I suppose a better way of doing it would be to make the wine/glass curve
match the glass inner surface exactly, and then scale the wine by
<0.999,1,0.999> or something. Must remember that! :-)
