Subject: [PATCH] Use available geometry when maximized.
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

Use the available geometry as a maximized window would fit on the
desktop in the available area (some space is used up by task bar,
system menu, etc.) as opposed to the fullscreen geometry which
would be the entire screen.
