 I think I disagree here. I don't see any compelling reason to have a separate 
type for override-redirect windows and IMHO it will avoid about as much 
confusion as it will create:

- there are already ways how to find if a window is normal managed window or 
not, so why separate two things that are exactly the same except for this 
detail?

- who can guarantee that eventually some of the types wouldn't be better as 
managed windows (NOTIFICATION may seem like a possible candidate)? Especially 
then things would get confusing.

 I suggest extending the normal _NET_WM_WINDOW_TYPE list and explicitly 
mentioning that both managed and override-redirect windows may have it set, 
with these being for managed and these for override-redirect ones (and say 
that WMs should cope with the override-redirect ones set on normal windows, 
just like they cope with unknown types).


 I don't actually do any graphics-related stuff, but the rest seems fine to 
me.
