As Warp says, its not really designed for recursive raytracing. There 
**are** hybrid applications that do fairly decent results, which 
probably do use it to speed things up a bit, **however** those systems 
are intended for production level systems, where speed is considered 
more important than realism. Since POVRay's primary goal is to generate 
the more realistic physical model possible, and short cuts that could be 
used to produce a movie, or the like, by side stepping, short cutting, 
or even ignoring, certain methods, in favor of speed, are "not" the 
intended goal here. Mind you, I wouldn't mind some of those short cuts, 
since its damn near impossible to do some things the "right" way, and 
certainly not in a sane span of time. But, short of adding those in as 
optional, so those in "production" level fields could use them, while 
leaving the normal methods intact, there isn't a benefit to the intent 
of the project to do that.

About half the people here would scream bloody murder and try to beat 
you to death with a checker plane if you tried to add shortcuts, never 
mind that there aren't a lot of free rendering systems that are as good, 
and also use those short cuts. Most of the other half would still be 
busy sharpening the edges of their triangle primitives, just in case 
your suggestion did break the physical based systems already in there. 
lol But, I think you see what I am getting at. Even if some of us would 
find it useful to take short cuts, its *not* what the program is 
supposed to be designed for, and what it *is* intended for isn't 
functionally possible in current GPUs.
