Sometimes it's best to just push it back out into the wild.

I went looking for sslt scene code, and that rotating pyramid again...
and got sidetracked.

Here's some granite with HDR lighting and radiosity.
I noticed that I probably didn't scale the texture properly, and so I can't
really see any of the veins.  In my readings, clipka mentioned that having the
mm_per_unit setting was there to decouple the texture from POV-units and so be
independent of scaling effects.  We might want to do similar with a
default-if-not-supplied, and a debug/warning message saying what it got set to.

I think that sometimes it is a bit slow to render - depending on how the scene
is set up.   Maybe have some quick-color definitions set up.  For ridiculously
high quality, I'm guessing we'd want some switchable reflection built in as well
for the same not0 reasons.
