I've implemented it in AfterStep devel (1.9) series, and since it was a
change ( like 50% of the code affected ), I'm pretty sure that it will
be changed back :)
E DR16 seems to work correctly, except for the fact that after initial
forgets gravity of the window and all further move/resizes are done as if
window had a NorthWest gravity (and that sucks).
Surprisingly I've not seen too many problems with that, except for XV, that
Center gravity but never actually requests it.

Frankly I don't see a 100% reliable way to test for compliance.
The only possible way would be to do XMoveWindow twice - in case first move
landed you in unexpected location - adjust position by the difference and
second move into this adjusted position. But again I can see problems with
What I ended up doing was a private interface between AfterStep modules and
AfterStep itself, allowing for exact positioning of window's frame, in
implement all those animations and placements of Wharfs etc. But obviously
will not work for general purpose widget set.
IMHO such a widely used things as Qt and GTK should stick to the rules,
and made all the lazy WM developers get off their butts and fix their stuff
Otherwise we'll never get out of the mess we are in right now.
