+This property MAY be set by the Client if the window is to reserve space at the edge of the monitor. The property contains 4 cardinals specifying the area of the reserved space. All coordinates are root window coordinates. The client MAY change this property at any time, therefore the Window Manager MUST watch for property notify events if the Window Manager uses this property to assign special semantics to the window.

+The purpose of struts is to reserve space at the borders of the monitors. This is very useful for a docking area, a taskbar or a panel, for instance. The Window Manager should take this reserved area into account when constraining window positions - maximized windows, for example, should not cover that area.

+Struts MUST be specified in root window coordinates, that is, they are not relative to the edges of any view port or Xinerama monitor. The Client MUST ensure that one of the largest edge of area is positioned at monitor edge and Window Manager MUST ignore this strut if Client fails to do that!
