[vtkusers] 3dWidgets - turn off feature (not bug) for picking widgets even behind other actors

[David E DeMarle]

I don't see an easy way to do that. To make it happen you would have to make
a change where vtkImagePlaneWidget calls this->PlanePicker->GetPath(). The
change would do something like
call this->PlanePicker->GetActors() and GetPickedPositions() and then do
something more inteligent to decide what prop is nearest for the pick.
