Not only can the window be off the screen, but it can itself vary in
depth.  If the corresponding sides of the masks are not parallel lines,
the fused window can be given its own binocular disparity.  In other
words, the plane of the window need not be parallel to the image plane.
I have seen this done with stereoviews, and the results can be quite
entertaining and surprising when combined with an appropriate scene.

To see the stereo window only as "an uninteresting hole through which we
view an interesting stereogram" is unduly limiting, IMO.
