[openbox] Gnome 3 shell

[Johan Vromans]

Fedora 15 provides the openbox-gnome package, which integrates openbox
in the 'modern' GNume environment.

It seems to work well, for one thing. The 'modern' Gnome panel
(actually, the Gnome3 fallback panel) is hardwired to occupy the top and
bottom 32 pixels. A window mapped at 0+0 will therefore be obscured for
32 pixels by the top panel.

Is there a way to have openbox exclude these areas?

I tried setting the top and bottom margins:

  <margins>
    <top>32</top>
    <bottom>32</bottom>
    <left>0</left>
    <right>0</right>
  </margins>

but windows mapped to 0+0 will still appear at the real top edge.
