    window/x11: Allow window resize while moving
    
    Commit f2328f11 would ignore any ConfigureRequest from X11 clients while
    there is an interactive user operation in progress.
    
    Yet, the user should be allowed to move a window while the X11 client is
    resizing it, as the two operations are not intrinsically incompatible.
