Ok, either I'm confused, or the whole net is confused!  When I think
of a transparent object, I automatically think of refracted rays.
How can you have a transparent object with no refraction effects and
still keep it transparent is something that my mind can't conprehend!!
In any raytracer that I've dealt with, if I set the refractive color to be
[ 0 0 0 ], I don't see any transparency effects.
If you mean the refraction index == 1, then I think that the wording
is wrong..

So, what is it?  Am I confused, or the net is confused?
