    Ignore spurious configure_area events.
    
    Colin Watson reports that on pre-releases of Ubuntu 18.04, configure
    events which don't actually involve a change of window size show up
    annoyingly often. Our handling of configure events involves throwing
    away the backing Cairo surface, making a fresh blank one, and
    scheduling a top-level callback to get terminal.c to do a repaint and
    populate the new surface; so a draw event before that callback occurs
    causes the window contents to flicker off and on again, not to mention
    wasting a lot of time.
    
    The simplest solution is to spot spurious configures, and respond by
    not throwing away the previous Cairo surface in the first place.
