  * interface elements requiring management by the compositor, such as

  * xdg_surface roles.
  *
  * Creating an xdg_surface does not set the role for a wl_surface. In order
  * to map an xdg_surface, the client must create a role-specific object
  * using, e.g., get_toplevel, get_popup. The wl_surface for any given
  * xdg_surface can have at most one role, and may not be assigned any role
  * not based on xdg_surface.
  *
  * A role must be assigned before any other requests are made to the
  * xdg_surface object.
  *
  * The client must call wl_surface.commit on the corresponding wl_surface
  * for the xdg_surface state to take effect.
  *
  * Creating an xdg_surface from a wl_surface which has a buffer attached or
  * committed is a client error, and any attempts by a client to attach or
  * manipulate a buffer prior to the first xdg_surface.configure call must
  * also be treated as errors.
  *
  * After creating a role-specific object and setting it up, the client must
  * perform an initial commit without any buffer attached. The compositor
  * will reply with initial wl_surface state such as
  * wl_surface.preferred_buffer_scale followed by an xdg_surface.configure
  * event. The client must acknowledge it and is then allowed to attach a
  * buffer to map the surface.
  *
  * Mapping an xdg_surface-based role surface is defined as making it
  * possible for the surface to be shown by the compositor. Note that
  * a mapped surface is not guaranteed to be visible once it is mapped.
  *
  * For an xdg_surface to be mapped by the compositor, the following
  * conditions must be met:
  * (1) the client has assigned an xdg_surface-based role to the surface
