/**
* A reference implementation how to use ivi-hmi-controller interface to
* interact with hmi-controller. This is launched from hmi-controller by using
* hmi_client_start and create a pthread.
*
* 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.
