The new 'Terminal_session::size_changed_sigh' RPC function registers a signal handler that is triggered each time when the terminal size changes. It enables the client to adjust itself to the new size by subsequently calling the 'size' RPC function. Of all terminal servers, only the graphical terminal triggers this signal.
