++ This interface is implemented by servers that provide IVI-style user interfaces.
++ It allows clients to associate a ivi_surface with wl_surface.

++ <request name="surface_create">
++ <description summary="create ivi_surface with numeric ID in ivi compositor">
++ This request gives the wl_surface the role of an IVI Surface. Creating more than
++ one ivi_surface for a wl_surface is not allowed. Note, that this still allows the
++ following example:
++
++ 1. create a wl_surface
++ 2. create ivi_surface for the wl_surface
++ 3. destroy the ivi_surface
++ 4. create ivi_surface for the wl_surface (with the same or another ivi_id as before)
++
++ 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.
++ The server regards following cases as protocol errors and disconnects the client.
++ - wl_surface already has an nother role.
++ - ivi_id is already assigned to an another wl_surface.
++
++ If client destroys ivi_surface or wl_surface which is assigne to the ivi_surface,
++ ivi_id which is assigned to the ivi_surface is free for reuse.
