    GtkTimeline: don't look when animations are disabled
    
    Otherwise, we end up doing maximal work with minimal effect, and
    bring the X server to 100% CPU. Note that this makes spinner widgets
    look really unclear, but they really have to be changed to adapt
    to enable-animations == FALSE at the widget level.
