Thanks.  I was pretty much sure that's what you meant, but with all
the back and forth, there was a tiny bit of confusion left in my
brain, thanks for the clarification.

As Brian pointed out, they bring in a C dependency we'd rather avoid
if we can (and if it can be avoided with minimal cost).  Barry
outlined the solution with more detail than my flaky sketch, and I
don't see any problem with that approach, so I think we can use that.

Well, thanks to you for having the patience to sort all of this!  Good
luck with the Mayavi week, let us know how it all goes!  In the
meantime, we've got plenty to stay busy here :)
