[vtkusers] How to make the outline actor for picking invisible?

[An Jiye]

I made some other tests. I think the problem lies in the vtkPropPicker.

In my tests, no matter what actor I added to the renderer and set its
PickableOff, it CAN be picked. This only happens when there is an a pickable
actor lies under the unpickable actor. For example, an isosurface is
pickable, a sphere isn't pickable, when I rotate the camera so that it looks
the sphere is on the pickable surface, I will get the picking position which
belongs to the sphere.

Does it due to the internal picking strategy of vtkPropPicker? Can this be
solved?
