[vtkusers] vtkImageViewer --> SetColorWindow , SetColorLevel

[Joeri Nicolaes]

Hi Serhat,

With the SetColorWindow and SetColorLevel methods you can perform a gray
scale transformation. See attach (windowlevel.jpg) for a figure that shows
the significance of window and level. If you read in medical images in DICOM
format, the window and level configuration of the original image are
mentioned in the DICOM header (tags (0028,1050) and (0028,1051) ).

Greetz,

Joeri
