Subject: [PATCH] desktop icons patch

New windows that has the _NET_WM_WINDOW_TYPE_DESKTOP window type
will not be managed by dwm.

Example programs that this applies to:
   - pcmanfm --desktop
   - nautilus -n (legacy)
   - nemo-desktop
   - caja --force-desktop --no-default-window

Note that these applications have a tendency of managing the
background wallpaper as well, the exception being nemo-desktop
where it appears to just be transparent if a compositor is used.
