[vtkusers] zoom operation

[Mark Wyszomierski]

Hi all,

I was using vtkImageViewer2 to display an image, simply because I
wanted panning/zooming taken care of, but now it is overkill for what
I am doing.

Is there any class or reference I can use for performing a zoom
operation on an image matrix? Especially one that would support
fractional zoom values,

Thanks,
Mark
