Renderer demo: Code review, please?

Colin, thanks for your very helpful feedback! I've refactored the code  
to implement most of your suggested changes, and to tighten it up a bit.

I have re-organized demo.render(), but because of other refactoring I  
did, it doesn't break down quite as nicely into the sections you've  
described. I'd appreciate a quick look at what I've done...

Yes, it's really almost not helpful at all as it is. I'll have a look  
at that library, to see if it has anything useful. Otherwise, I might  
just manually code something that pretty-prints it myself...

Again, thanks for the review! I know you're really busy.
