   Yes,  but you should not use it except under some very special
   circumstances:

	<special circumstances edited...>

   Use of override-redirect under other circumstances is "strongly
   discouraged" (see ICCCM section 4.2.2).

In my application I map a full-screen input-only window that I use to turn
the X mouse into a virtual trackball.  I certainly don't want the user to
have to "position" this invisible window.  So override-redirect is useful
in other cases as well as the two reported above.
