+ * A reference implementation how to use ivi-hmi-controller interface to

+ *
+ * The basic flow is as followed,
+ * 1/ read configuration from weston.ini.
+ * 2/ draw png file to surface according to configuration of weston.ini
+ * 3/ set up UI by using ivi-hmi-controller protocol
+ * 4/ Enter event loop
+ * 5/ If a surface receives touch/pointer event, followings are invoked
+ * according to type of event and surface
+ * 5-1/ If a surface to launch ivi_application receive touch up, it execs
+ * ivi-application configured in weston.ini.
+ * 5-2/ If a surface to switch layout mode receive touch up, it sends a request,
+ * ivi_hmi_controller_switch_mode, to hmi-controller.
+ * 5-3/ If a surface to show workspace having launchers, it sends a request,
+ * ivi_hmi_controller_home, to hmi-controller.
+ * 5-4/ If touch down events happens in workspace,
+ * ivi_hmi_controller_workspace_control is sent to slide workspace.
+ * When control finished, event: ivi_hmi_controller_workspace_end_control
+ * is received.
