    Select correct client window in WM’s using virtual roots
    From bug 2185¹
    
    When manually selecting a window, xprop finds the top-level window containing
    the pointer and uses XmuClientWindow to attempt to find a client window having
    WM_STATE set.
    
    In a WM using virtual roots (e.g. enlightenment, desks other than first) this
    fails beacuse the top-level window is a virtual root, and XmuClientWindow seems
    to find the first client having WM_STATE set, which only by coincidence will be
    the one the user intended to select (i.e. containing the pointer).
    
    The solution is to descend the window hierarchy at the pointer location to find
    a window with WM_STATE set.
