contourf bug

Jordan, Correct. I sent John a patch to fix that, but it

Thanks for the reminder here. I was unaware that there was an
outstanding patch on this one. Would it be too much trouble to roll
up a new one against CVS, or even just resent the original one,
because you've sent me a number of patches and I'm not sure which one
this one is.

Or better yet, send me an sf ID and I'll add you to the commit list.
