[vtkusers] Disable mouse interaction on overlaid image

[David Gobbi]

Great.  I've made one more minor change, I renamed
SetCurrentImageToNthImage() to SetCurrentImageNumber().
https://gitlab.kitware.com/vtk/vtk/merge_requests/1421/diffs

I'll try to get this change merged into VTK.

Cheers,
 - David
