 	This message allows an application to initiate window movement or resizing.  This allows the application to define its own move and size "grips", whilst letting the window manager control the actual move/resize.  This means that all moves / resizes can happen in a consistent manner as defined by the WM.

+Rationale: For window managers that display a title different from the _NET_WM_NAME or WM_NAME of the window (i.e. xterm <1>, xterm <2>, ... is shown, but _NET_WM_NAME / WM_NAME is still xterm for each window). This property allows taskbars / pagers to display the same title as the window manager.
