[vtkusers] Disable mouse interaction on overlaid image

[Jothybasu Selvaraj]

Hi David

I am not familiar with using Gitlab. So, I subclassed
vtkInteractorStyleImage and override SetCurrentImageToNthImage().

Still it didn't work, because the layer number is hardcoded into
StartWindowLevel()
with this->SetCurrentImageToNthImage(-1); So the mouse only interacts with
the last image. I changed it to "0" so that it pick the first image.

It solves my problem. I only want to interact with the first image :).


Thank a lot for your inputs.


Cheers

Jothy
