36 Reference protocol to control a surface by server.
37 To control a surface by server, it gives seat to the server
38 to e.g. control Home screen. Home screen has several workspaces
39 to group launchers of wayland application. These workspaces
40 are drawn on a horizontally long surface to be controlled
41 by motion of input device. E.g. A motion from right to left
42 happens, the viewport of surface is controlled in the ivi-shell
43 by using ivi-layout. client can recognizes the end of controlling
44 by event "workspace_end_control".
