Reference protocol to control a surface by server. To control a surface by server, it gives seat to the server to e.g. control Home screen. Home screen has several workspaces 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 by event "workspace_end_control". hmi-controller loaded to ivi-shall implements 4 types of layout as a reference; tiling, side by side, full_screen, and random. home screen is a reference implementation of launcher to launch wayland applications. The home screen has several workspaces to group wayland applications. By defining the following keys in weston.ini, user can add launcher icon to launch a wayland application to a workspace. [ivi-launcher] workspace-id=0 : id of workspace to add a launcher icon-id=4001 : ivi id of ivi_surface to draw an icon icon=/home/user/review/build-ivi-shell/data/icon_ivi_flower.png : path to icon image path=/home/user/review/build-ivi-shell/weston-dnd : path to wayland application
