commit feac0759522cbdc3e61ccfa373df735903c5cb27
Author: Keith Packard <keithp@koto.keithp.com>
Date:   Wed Oct 17 11:42:28 2007 +0800

    Make config file preferred mode override monitor preferred mode.
    
    Add a new even-more-preferred bit to each mode which is used to make config
    file preferences selected instead of the monitor preferred mode.
