++ <interface name="agl_shell" version="3">
++ <description summary="user interface for Automotive Grade Linux platform">
++ Starting with version 2 of the protocol, the client is required to wait
++ for the 'bound_ok' or 'bound_fail' events in order to proceed further.
++
++ In case the client gets a 'bound_fail' event then it should consider that
++ there's another client already bound to the agl_shell protocol.
++ A client that receives a 'bound_ok' event should consider that there's
++ no other client already bound to the interface and can proceed further.
++
++ If the client uses an older version of the protocol it will receive
++ automatically an error and the compositor will terminate the connection,
++ if there's another client already bound the interface.
++
++ If the client receives the 'bound_fail' event and attempts to use the
++ interface further it will receive an error and the compositor will
++ terminate the connection. After the 'bound_fail' event was received the
++ client should call the destructor, which has been added with version 2
++ of the protocol. The client is free to try at a later point in time to
++ see if it will receive the 'bound_ok' event, but there's no explicit way
++ of finding out when that event will be delivered.
++ It is assumed that it can infer that information through other
++ means/other channels.

++ This gives the client an opportunity to set up and configure several
++ surfaces into a coherent interface.

++ The client that binds to this interface must send this request, otherwise
++ they may stall the compositor unnecessarily.

++ If this request is called after the compositor has already finished

++
++ The surface must have a "desktop" surface role, as supported by
++ libweston-desktop.
++
++ Only a single surface may be the background for any output. If a

++ Set the surface to act as a panel of an output. The 'edge' argument
++ says what edge of the output the surface will be anchored to.
++ After this request, the server will send a configure event with the
++ corresponding width/height that the client should use, and 0 for the
++ other dimension. E.g. if the edge is 'top', the width will be the
++ output's width, and the height will be 0.
++
++ The surface must have a "desktop" surface role, as supported by
++ libweston-desktop.
++
++ The compositor will take the panel's window geometry into account when
++ positioning other windows, so the panels are not covered.
