[vtkusers] iterating through vtkImageStencilData

[Prathamesh Kulkarni]

Hi David,

Thanks for the direction. The documentation does not make it very clear to
me. Could you please point/cook me a little example for accessing pixel
values of vtkImageStencilData using the method you suggested? If I am able
to do it, I'll post it out.
