[vtkusers] vtkImagedata and vtkRenderWindow

[David Gobbi]

If you are using vtkImageActor or vtkImageViewer2 to display the image, then the resize should be
automatic.  Generally these are the two classes
you should use for image display.


If you are using vtkImageMapper or the old vtkImageViewer, then you need
to add an observer for the "StartEvent" of the renderer.  This event is generated immediately
before the renderer updates the pipeline and paints the window.  In the callback for the observer,
you have to resize the
image using a resample filter based on the width and height of the
renderer.
