[vtkusers] VtkImageViewer2 disabling window level

[Leonardo M. Ramé]

Hi, I'm creating an image viewer based on VTKImageViewer2, and I want to
create a Toolbox where the user picks an option, like "circle" or "box",
then drag that to the image to show it.

My problem is, whenever the user drags anything to the viewer, it does
Window/Level. How can I disable WindowLevel?
