Yes, of course it has a border.  But the border doesn't function
entirely the same way as the mask of a stereo slide or print.

The difference as I see it is that in a stereo slide or print pair, the
mask is binocular.  You can actually give this window a varying position
in 3D space, since the left and right masks can have disparity just like
the images themselves.  You can't do this with the physical border of a
lent. no matter how you try, because there is just one border seen by
both eyes.

Having said that, it seems that you ought to be able to produce the
effect by creating the window mask *within* the image, and then you
would indeed have a stereo window in the slide/print pair sense.
