From ddc84d0a4abfe46b6cfac00340d1ad88e6a28009 Mon Sep 17 00:00:00 2001

Subject: Set properties to work better under metacity, per the extended window
 manager hints spec: 1) Set _NET_WM_WINDOW_TYPE to
 _NET_WM_WINDOW_TYPE_UTILITY, so that metacity does not add zephyrgram windows
 to the task list. 2) Set _NET_WM_DESKTOP property to 0xFFFFFFFF by default,
 so that zephyrgram windws appear on all workspaces.  Add the "allDesktops"
 resource allowing users to override this behavior.
