OK, I am totally confused.  Ron Labbe et al. said that they
think of the scene moving with respect to a fixed window, i.e. a
flower comes back and forth with respect to the window.  I, on
the other hand, think of the window moving with respect to the
scene.  For example, when others see the scene coming closer to
the window, I see the window GROWING LARGER and moving away from
me.  This works better in a viewer obviously because in
projection you have a fixed place in space (usually the screen)
where the window is formed.
