Thanks. I implemented it that way, and it seems to be working so far, so I
believe that everything is fine.

You're too right. Unfortunately, I can go for a while and do a really good job
of commenting, and then I'll slack off for one reason or another (usually as a
result of not coding for a few weeks), and then write huge quantities of code
with no comments at all.
Right not I think I'm doing OK on comments in my new code. And since I started
working on it again a few weeks ago after many months of no work, I'm trying to
add comments to the sections of the existing "new" code that confused me.
I think I have correctly functioning BFC working at this point (I'll be more
confident after I've played with more models). Mind you, it slows down
rendering on my current video card, but it does seem to at least work.
