support for resizing. To maximize window we need to use
_NET_WM_STATE_FULLSCREEN, but it doesn't tell use that it supports it.
New IceWM also doesn't support layers in fullscreen mode, changing it
doesn't change window position (again, "-icelayer" doesn't fit well).
Also while fixing fvwm metacity got broken again, so there is a new
hack or it, and small fix in code for openbox.
Now it should work on almost everything.
