[gradsusr] smoothed shadings in GRADS

[Jeff Duda]

I'm not sure what to say then. Perhaps the smth9() function only works on
horizontal fields (that's all I've ever used it on)?

Perhaps something very clever will be needed. Or you might have to perform
the smoothing in an alternate data set outside of grads. Or you may be out
of luck on this option. I'm not sure. Hopefully someone else can chime in
with better advice.

Good luck!

Jeff
