vtkSMCameraLink propagated start/end interaction events through the links. This was done a long time ago when we wanted to support "linked" interaction undo/redo stacks -- something we no longer do. Also, that's conceptually wrong. Observers listening to StartInteractionEvent on a view may think a user is interactive with multiple views at the same time is they are linked together via vtkSMCameraLink. Hence removing this logic to propagate these events. vtkSMCameraLink separately manages whether to call InteractiveRender on StillRender on the view and that part is unaffected.
