Ok... if you want to reflect red, you use
  reflection <1,0,0>

But what if you want to reflect a complex pattern???  Since "finish"
cannot currently be patterened, this is not possible.

But think about this.  If you specify the 'metallic' keyword, the highlights on
your objects will take on the color of the object's pigment.  A highlight is
basically a faked blurry reflection of the light source, right?  So, doesn't it
make sence that if you specify 'metallic', all reflection should take on the
color of the pigment?  Ok, so maybe that would be too drastic and would break
too many scenes. But how about this:  a 'metallic_reflection' flag that would
make reflections reflect the color of the pigment.  Thoughts?

I'll probably implement this in the next version of UVPov (photon mapping
patch), but I do want to hear your comments.

Sounds good. As long as it doesn't break any old scenes it never
hurts to add a reasonable feature. I haven't had the need to reflect
any other color than gray but I guess it could come in handy
sometimes.

IIRC, Wyzard has implemented this very thing as a new keyword in the
most recent version of Wyzpov.

Which reminds me, I'm going to have to incorporate wyzpov into uvpov.

Maybe it's because I have an older version of the wyzpov source, but one
thing that's awkward about it is that reflection has been completely
replaced.  Anyway, just something to look out for.

I tried to patch uvpov with it, but unfortunately it doesn't seem to
work right.  Even worse is that it runs and renders fine - looks almost
like it's reflecting backwards or something...wierd.  

I should really get the latest version of the patch I guess. :)

Forgive me for being so presumptuous as to ask, but why?  I can just 
give you my current superpatch sources, and you can have everything
that's in there, including the UVpov that was current a few weeks ago
(no photon mapping yet, as I decided to wait until it's out of alpha. :) )
and a version of Wyzpov from a while ago (no metallic reflection patch
yet, but that's not so hard to add.)

Yes, I know, I haven't done so good at getting out regular updates. 
I'm working on some processes that should streamline that a bit, 
including putting the documentation in a format that I can actually
use instead of in Word.
