[vtkusers] viewport problems

[Clinton Stimpson]

My problem is not the front and back clipping planes.  My sphere isn't being
cut off from the front or the back.
vtkRenderer::ResetCamera does the fit to make the model fit in the window.

But my case is where the window has a smaller width than height.  VTK can't
fit the object in the window.  You can do this in ParaView.  Make a sphere,
or whatever you want, then resize the window such that it is taller than it
is wide.  And keep making the width smaller, the object doesn't shrink to
fit the window.  Hit the "Reset View" button and it doesn't make the sphere
fit in the window.  If you resize the window so that you make it shorter
than it is wide, the object will shrink in size to fit the window.

It isn't just my app, it happens in ParaView too.
