I know ... I could share the source in private, put as it is likely to be my
competition entry, I'm unwilling to share it in public before the deadline.

That's what I'd learned from the grapevine, but it works in my scene.
In fact, before I pumped it up the back of my room was having a night when
close to windows it was a bright sunshine.  Anyway it doesn't slow the
rendering very much, hardly noticeably; I'd guess that to be due to
adc_bailout, but then I couldn't explain why it brightens up the room!

I really, really, /really/ am going to sit down with radiosit.cpp once
I can get my mind off modelling this scene! :)

Rays pass through four surfaces (two per window) of differing IOR on their
way out; that's four levels for ray tracing, and I'm assuming it's also
four radiosity recursions.  This is not so?
