[vtkusers] Resize vtkImageData

[David Gobbi]

This is something that vtkImageReslice will work nicely for.
Set the OutputExtent to the new image dimensions,
and set the OutputOrigin to the new coordinates of
the lower-left corner (subtract the pad size times the
pixel spacing from the old Origin).
