This removes link from ivi_id to wl_surface and destroys ivi_surface. The new visibility state is provided in argument visibility. If visibility is 0, the surface has become invisible. If visibility is not 0, the surface has become visible. The configure event asks the client to resize its surface. The size is a hint, in the sense that the client is free to ignore it if it doesn't resize, pick a smaller size (to satisfy aspect ratio or resize in steps of NxM pixels). The client is free to dismiss all but the last configure event it received. The width and height arguments specify the size of the window in surface local coordinates. This interface is implemented by servers that provide desktop-style user interfaces. It allows clients to associate a ivi_surface with a basic surface. 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.
