 // Called when the user wants to close the panel or from the shutdown process.
 // The Browser object is in control of whether or not we're allowed to close. It
 // may defer closing due to several states, such as onbeforeUnload handlers
 // needing to be fired. If closing is deferred, the Browser will handle the
 // processing required to get us to the closing state and (by watching for
 // all the tabs going away) will again call to close the window when it's
 // finally ready.
 // This callback is only called if the standard Close button is enabled in XIB.
