_NET_WM_ALLOWED_ACTIONS

["Oleg Sukhodolsky" <son two gmail com>]

Hello,

Is there any _standard_ way to disable the Minimize (or Maximize, or
Close, whatever) menuitem on the system menu (accessible via
Alt-Spacebar or Alt-RightClick under Metacity)?
I've read the _NET_WM_ALLOWED_ACTIONS spec, but it's not clear whether
this is client- or WM- managed hint...

Thanks in advance, Oleg.
