Don't wait for a response back from the window manager if our size hasn't

	* gtk/gtkwindow.c (gtk_window_move_resize): Don't wait for a
	response back from the window manager if our size hasn't changed
	since we won't get a response back from the window manager;
	there was code in there to do this, but it was in the wrong
	place so if the hints change and the size didn't we'd expect
	a response.

	Also, optimize the position-only-changed case by running
	the resize queue immediately, and clean up some comments
	for the changes.
