-        implementation-dependent - do not assume that this region will not
-        actually be occluded.
-
-        A positive value is only meaningful if the surface is anchored to one
-        edge or an edge and both perpendicular edges. If the surface is not
-        anchored, anchored to only two perpendicular edges (a corner), anchored
-        to only two parallel edges or anchored to all edges, a positive value
-        will be treated the same as zero.
-
-        A positive zone is the distance from the edge in surface-local
-        coordinates to consider exclusive.
-
-        Surfaces that do not wish to have an exclusive zone may instead specify
-        how they should interact with surfaces that do. If set to zero, the
-        surface indicates that it would like to be moved to avoid occluding
-        surfaces with a positive exclusive zone. If set to -1, the surface
-        indicates that it would not like to be moved to accommodate for other
-        surfaces, and the compositor should extend it all the way to the edges
-        it is anchored to.
-
-        For example, a panel might set its exclusive zone to 10, so that
-        maximized shell surfaces are not shown on top of it. A notification
-        might set its exclusive zone to 0, so that it is moved to avoid
-        occluding the panel, but shell surfaces are shown underneath it. A
-        wallpaper or lock screen might set their exclusive zone to -1, so that
-        they stretch below or over the panel.
-
-        The default value is 0.

-        surface. For layers below the shell surface layer, the seat will use
-        normal focus semantics. For layers above the shell surface layers, the
-        seat will always give exclusive keyboard focus to the top-most layer
-        which has keyboard interactivity set to true.
-
-        Layer surfaces receive pointer, touch, and tablet events normally. If
-        you do not want to receive them, set the input region on your surface
-        to an empty region.

-
-        The size is a hint, in the sense that the client is free to ignore it if
-        it doesn't resize, pick a smaller size (to satisfy aspect ratio or
-        resize in steps of NxM pixels). If the client picks a smaller size and
-        is anchored to two opposite anchors (e.g. 'top' and 'bottom'), the
-        surface will be centered on this axis.
-
-        If the width or height arguments are zero, it means the client should
-        decide its own window dimension.
