+ 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 delivered. It is assumed that it can
+ infer that information through other means/other channels.
