	return value of XWithdrawWindow; it could indicate that the window
	wasn't successfully redrawn.

        * xterm.c (x_make_frame_invisible): Use XWithdrawWindow when
	available [HAVE_X11R4]; send the UnmapNotify event when
	appropriate [HAVE_X11]; just unmap the window if that's all that's
	needed [not HAVE_X11].

	* xterm.c (x_set_text_property): Removed; it's only called from
	one place.  Who wants *another* layer of indirection?

	* xterm.c: Use the FRAME_X_WINDOW macro, for readability.

	* xterm.c (x_death_handler): Renamed to x_connection_closed.
	(x_term_init): Use x_connection_closed as the SIGPIPE handler.

	* xterm.c (acceptable_x_error_p, x_handler_error_gracefully,
	x_error_handler): Removed; you can't catch X errors this way,
	since you can't perform X operations from within an X error
	handler, and even though we call error, we're still within an X
	error handler.
	(x_error_quitter, x_error_catcher): New functions, for panicking
	on and catching X protocol errors.
	(x_caught_error_message): Buffer for caught X errors.
	(x_catch_errors, x_check_errors, x_uncatch_errors): New functions
	for catching errors.
	(x_term_init): Set the error handler to x_error_quitter, rather
	than x_error_handler.

	* xterm.c (x_death_handler): Renamed to x_connection_closed.
	(x_term_init): Use x_connection_closed as the SIGPIPE handler.
