   Just to save you some effort: please don't work on any of these before
trying the new feature on beta 39... :) This advice will apply also for
arblick's project, BTW.

POVRAY 3.9!!!!!!!!!!

Time to be belligerent, or at least annoying.  ;)

Where, where, where, where, where, where, where, when, when, when, where, where,
where, where?!?!?

(P.S.  Disregard my post about being in the wrong room.  I was posting that on
the wrong website.  Doh!!!  Many apologies.)

beta 39 of povray 3.7, not povray 3.9. it will be out next week and has the
means to do texture baking.

I've just updated this with details of the new max depth parameter (which
I'm just about to check into trunk).

Well, I must say it's very strange, as I've been thinking about this 
feature on-and-off for about three weeks now. Can't remember what 
exactly got me to thinking about it. It's very cool that a form of 
texture-baking is finally making its way into POV! This should make 
proximity patterns for meshes faster :)

   I never doubted you were some sort of POV-Psychic... :)

   A lot faster!
