So I had this test scene set up for making sure old files I'd converted 
from whatever format to mesh2 were all pointing to the right texture 
paths and/or had nice-looking POV-native textures.  All well and good, 
more or less, also playing around with changed POV 3.7 syntax from 3.5.

Hmm.  I haven't tried anything with photons, yet.  Turn on that block of 
code.

Strange, no matter how I tweak the settings there, nothing is changing...

Realise I had 'shadowless' set on my light source.  Turn that off.

Forget to lower photon settings back to something sane.

13 hours later...

It would be nice to have something for the photons to show up on...
Now, you have a totaly black background or surface. You may have 
100000000 photons, but they never show.
My bet is that even without any photons, that scene will look the same, 
or very similar.

Don't forget that shadowless also prevent any highlight.
You don't need photons to have highlights.
You don't need photons to have dispersion work.

Tried that again.  Needs some work, but it's a lot closer to what I had 
in mind (and my new computer is fast enough that I can /play around/ 
with settings that would take a day to do a test render in POV 3.5 on my 
other computer).
