Feat: Rudimentary dielectric... but broken

Browse Source 
Dielectric material matching Raytracing in a Weekend book chapter 10.2.
But it isn't right. The spheres turn into solid black holes.

As I'm making the commit, I've found the problem. I'm separating it out
so I can tag it and explore the code a bit more. See the step-by-step
changes, and such.
