/**
* A reference implementation how to use ivi-layout APIs in order to manage
* layout of ivi_surfaces/ivi_layers. Layout change is triggered by
* ivi-hmi-controller protocol, ivi-hmi-controller.xml. A reference how to
* use the protocol, see hmi-controller-homescreen.
*
* In-Vehicle Infotainment system usually manage properties of
* ivi_surfaces/ivi_layers by only a central component which decide where
* ivi_surfaces/ivi_layers shall be. This reference show examples to
* implement the central component as a module of weston.
*
* Default Scene graph of UI is defined in hmi_controller_create. It
* consists of
* - In the bottom, a base ivi_layer to group ivi_surfaces of background,
* panel, and buttons
* - Next, a application ivi_layer to show application ivi_surfaces.
* - Workspace background ivi_layer to show a ivi_surface of background image.
* - Workspace ivi_layer to show launcher to launch application with icons.
* Paths to binary and icon are defined in weston.ini. The width of this
* ivi_layer is longer than the size of ivi_screen because a workspace has
* several pages and is controlled by motion of input.
*
* TODO: animation method shall be refined
* TODO: support fade-in when UI is ready
