The ivi compositor encountered warning while processing a request by this

warning_text. If the warning is detected, client shall destroy the ivi_surface
object.
When ivi compositor encounters warnings, a request is canceled and there is no
mapping from id_surface/wl_surface to this ivi_surface. Even if there is no
mapping but destroying this ivi_surface is recommended.

<description summary="create ivi_surface with numeric ID in ivi compositor">
surface_create will create a interface:ivi_surface with numeric ID; surface_id in
ivi compositor. These surface_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 surface_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.
Created ivi_surface notifies warnings when following situation happens,
- Invalid wl_surface is set. This happen if wl_surface is destroy before this.
- surface_id is already assigned by another application.
If a client sets a wl_surface to multiple id_surfaces, no warning is issued. Property
of the surface can be controlled by multiple ivi_surface. However this case shall
be avoided by a client.
