>+13. Pointer Barriers
>+
>+Compositing managers and desktop environments may have UI elements in
>+particular screen locations such that for a single-headed display they
>+correspond to easy targets according to Fitt's Law, for example, the top
>+left corner.  For a multi-headed environment these corners should still be
>+semi-impermeable.  Pointer barriers allow the application to define
>+additional constraint on cursor motion so that these areas behave as
>+expected even in the face of multiple displays.
>+
>+Absolute positioning devices like touchscreens do not obey pointer barriers.
>+There's no advantage to target acquisition to do so, since on a touchscreen
>+all points are in some sense equally large, whereas for a relative
>+positioning device the edges and corners are infinitely large.
>+
>+WarpPointer and similar requests do not obey pointer barriers, for
>+essentially the same reason.
