How to turn off autoscaling in Axes3D

Matt, just to let you know, axes3d is not really supported. We
include it because some people find it useful and we're hoping some
person (you!) will pick it up and run with it. This code was written
and generously donated by John Porter, who is too busy to maintain it
as are the other core mpl devels. So please use it and post problems,
but don't be surprised if noone comes to your aid. Most likely, you
will need to find and fix these bugs yourself as you can.

In general, you can turn off autoscaling with

  ax.set_autoscale_on(False)

Though I would have to dig through the code to see if this is
supported for Axes3d....
