[vtkusers] Crosshair on 2D medical image display

[Karthik Krishnan]

A vtkHandleWidget (with a vtkPointHandleRepresentation3D and a
vtkImageActorPointPlacer) should do the job for you. However the
interactions across the views will have to be handled by you, using a
callback-observer mechanism. Its appearance (red-blue-green lines) etc will
also have to tailored to your look and feel by subclassing the
representation.
