Crap! Is that why my colorbars from my pcolors (or was it pcolormesh?) never
worked right?  I have been making colorbars directly for a while now because
I couldn't figure out why those colorbars didn't work right.

I think I will file a feature request to fix this inconsistency.  Probably
will be a bit involved to fix it, though.
