You should use the setRange method of ScaleMap to reverse the
scales, so instead of having (-90, 90), you could have (90, -90).

At present there is no way to put the AxisScales on the "top"
of the 3D plot, although I'll keep that in mind for a
future enhancement.  (Don't hold your breath on getting that
any time soon though. ;-))
