       used to follow the same rules as above, but _Java_ Swing can't handle
       this. So just to appease Swing, when user = TRUE, we always send
       a synthetic ConfigureNotify to give the window its root coordinates.
       Lastly, if force_reply is TRUE, we always send a
       ConfigureNotify, which is needed during a resize with XSYNCronization.
