This is *great*!

I'm often in a situation where I have a reasonably simple scene that I
intend to animate, and want to preview it at some speed while maintaining
surface texture quality. Parsing tends to make up a large fraction of the
render time in some of these cases; it can even dominate. Being able to use
RTR as a sort of rapid flyby/flyaround mode is brilliant! I got about 1fps
at 160x128 on a complex scene involving complex meshes, refraction,
transparency, image maps and so on, which is many times faster than what
I'd get if I wanted to do the equivalent in 3.6 (due to the repeated
parsing). The machine is a lowly 2.4GHz P4.

The only outright issue I noticed was the first run on the RTR menger
example scene, when in my eagerness I forgot to set use_vidcap to 0 (I
don't have a webcam or other video source). This caused an "Access
violation exception" dialog to be shown, followed by an orderly shutdown of
POVWin. Setting use_vidcap to 0 removed the problem. I can reproduce this
problem on demand, should you want a dumpfile at this stage.
