_net_wm_state_fullscreen

[Iban <hatchond yahoo fr>]

Hi everyone,
I remember that we already talk about this on the list, but I can't find 
it in the archive (or it is unclear for me)
I have three questions

 - when (as a window manager) I receive a _net_wm_state_fullscreen 
message, may I, instead of undecorating the window, displace my 
decoration at the appropriated coordinates ?

 - in the same case shall I set _net_wm_state_maximize_vert/horz or not ?

 - Gerd Knorr already ask for this one, and the answer seems obscure to me:
  when an application wants to change the screen resolution we have two 
solutions (as far as I understood the thread): VidMode and Xrandr. But 
it does not tell me what I have to do ? (except that if everyone use 
Xrandr I should do the expected work, because the sizes of the root 
window has changed)

Best regards,
Iban.
