"_NET_WM_STATE_FULLSCREEN indicates that the window
should fill the entire screen
and have no window decorations. Additionally the Window
Manager is responsible for
restoring the original geometry after a switch from
fullscreen back to normal window."

As I understand the above quote it's the WM's
responsibility on application's
request to remove window decorations and resize a window to
fill the screen,
then restore its previous state when switching from a
fullscreen state.

So, all the checks metacity does for window decorations and
window size are
contradicting the spec IMO.

Also the fact that a window isn't resizeable means only
that it's not supposed
to be resizeable by a user, still allowing to resize it
programmatically.
