That's what I'm currently doing, but I'm not sure
if it works as we think it does. As far as I understand
the raytracing technique, POV will stay with ior 1.45 from
the glass until it hits the surface of the water, and gets
refracted the way it should when exiting a 1.33 ior to
1.00 ior (water to air). But I'm not too sure about that,
and also no quiet sure how I should test that...
