to group launchers of wayland application. These workspaces
are drawn on a horizontally long surface to be controlled
by motion of input device. E.g. A motion from right to left
happens, the viewport of surface is controlled in the ivi-shell
by using ivi-layout. client can recognizes the end of controlling
