[vtkusers] Disable mouse interaction on overlaid image

[David Gobbi]

Hi Jothy,

I've added a change so that SetCurrentImageToNthImage is public:
https://gitlab.kitware.com/vtk/vtk/merge_requests/1421/diffs

If you're not sure about how to get the changes with git, then you can
download the files here:
https://gitlab.kitware.com/vtk/vtk/raw/81d49118/Interaction/Style/vtkInteractorStyleImage.h
https://gitlab.kitware.com/vtk/vtk/raw/81d49118/Interaction/Style/vtkInteractorStyleImage.cxx

Please test to see if this solves the issue.

 - David
