parallel lens axes

[P3D John Bercovitz <bercov@xxxxxxxxxxx>]

You guys are saying the same thing, I think.  The axes of the 
lenses themselves are parallel or you would indeed get keystoning.  
However, lines drawn through the centers of the lenses and through
the centers of their corresponding images are not parallel.  If 
these words don't draw a good picture for you, use your web browser 
to get to:

and I'm sure you guys will see you're agreeing with each other.
