<description summary="server-side warning detected">
The ivi compositor encountered warning while processing a request by this
application. The warning is defined by argument warning_code and optional
warning_text. If the warning is detected, client shall destroy the ivi_surface
object.
When a warning event is sent, the compositor turns the ivi_surface object inert.
The ivi_surface will not deliver further events, all requests on it are ignored
except 'destroy', and the association to the ivi_id is removed. The client
should destroy the ivi_surface object. If an inert ivi_surface object is used as
an argument to any other object's request, that request will [produce a fatal
error / produce a warning / be ignored].

This interface is implemented by servers that provide desktop-style user interfaces.
It allows clients to associate a ivi_surface with a basic surface.

<request name="surface_create">
<description summary="create ivi_surface with numeric ID in ivi compositor">
surface_create will create a interface:ivi_surface with numeric ID; ivi_id in
ivi compositor. These ivi_ids are defined as unique in the system to identify
it inside of ivi compositor. The ivi compositor implements business logic how to
set properties of the surface with ivi_id according to status of the system.
E.g. a unique ID for Car Navigation application is used for implementing special
logic of the application about where it shall be located.
if a wl_surface which already has another role is set, the server regards this as
error and disconnects the client.
