[vtkusers] Moving a plane along normal

[Miro Drahos]

Hi Michael,
void vtkPlane::Push(double)  will do what you want: displace the plane 
in the normal direction.

You might want to look at vtkInteractionStyleTrackBallActor to see how 
objects are repositioned/reoriented in the space on mouse interaction.
HTH,
Miro
