Um... hmmmmm. No idea why that is, but your message here got me to trying
number_of_waves and I'm seeing once again what might have been a bug during
beta testing, which could be totally unrelated. However, then again it could
be related in at least some obscure way I guess. Unfortunately, I don't
recall what, if anything might have been done about it. I was a little
sparse on beta testing toward the end.

For instance: if global_settings {number_of_waves 10}} is used (the default)
I get a different (and incorrect) rendering from the next, or following,
render without changing its value. To see this happen yourself you'll need
to set another value, render, then change it to 10, render, and finally
render one last time after that. Take note of the appearance of the sphere
when 10 is used the first time. Of course, it might not happen for everyone.
