[vtkusers] Get bounding box for vtkPlanes?

[Robb Brown]

I have a vtkPlanes object and I'd like to pick a point on the surface 
of the cube that it encloses.  First off, is there a standard way of 
doing this?

My instinct was to create a polydata cube from the vtkPlanes and pick 
on that.  vtkCubeSource has a SetBounds() method (as does vtkPlanes), 
and I notice that vtkPlanes maintains its bounds as a private variable, 
but there is no vtkPlanes.GetBounds().  So how do I do this?

Thanks,

Robb
