the global using the bind request, the client should now
destroy that object.
The object remains valid and requests to the object will be
ignored until the client destroys it, to avoid races between
the global going away and a client sending a request to it.
Until the client destroys the object, the compositor will
ignore other requests to the object except that, for any
request that adds new objects to the compositor state,
the compositor will continue to add the new objects to
its state. These new objects transitively follow the same
rules.
