When a Galeon window is in full screen mode, its window decorations remain
visible.  The title bar provided by the window manager appears at absolute
X position (0, 0), with Galeon therefore offset down.  The bottom edge of
Galeon's area is pushed off the bottom of the screen by the same amount.

Galeon needs to suppress window manager decorations when in full screen
mode.  If that's not feasible, then perhaps it can simply compensate for
the geometry offset.

I know this can be done somehow, as this used to work correctly (in Galeon
1.0, I think).  So this is a regression.

As noted in the "OS Details" field, I'm using Sawfish 0.38.  I can
consistently reproduce the problem using the default Sawfish configuration
as provided by Ximian GNOME.
