Cleaner render of Rachel's hypnosis scene

When the hat started making Re Education, the tools it was working with were rather limited. While rendering global lighting and complex shadows was possible, the results varied widely from good, to acceptable, to just awful.

This is an example on the awful side. The shadowing up near the ceiling is like "Late 90's 256 color pre rendered background" awful. That would be fine were the hat making a retro themed visual novel (which it did consider).

But at the time this was a case of not being able to do better despite playing with a bewildering combination of light sources, so the hat simply had to make do.

However now that the hat knows a little more about 3D rendering and modeling in general, it has redone this background and employed a new renderer that handles lighting better:
