[vtkusers] Axis issues

[Gerrick Bivins]

Ok. I understand what you are trying to do now. I don't think
vtkCubAxesActor gives you the access to underlying structures that you'd
need to customize the actor (Xaxis,Yaxis,Zaxis). It probably could be
modified to do so by adding some extra Get/Set methods to the interface.
Probably should log a bug/feature request.

I'm actually having the same problem you are having with the "offset" issue
but mine is occurring when I scale the CubeAxesActor. The class doesn't
provide an interface to set the range of values to label along the axes so
any modifications to it's placement, changes the values displayed!!! OUCH.
This should also probably be logged as a bug/feature request.
