    elements: Queue for redraw only the KeyframeCurve
    
    The "plot-changed" signal of the KeyframeCurve was emitted in a single
    place and used only by its TimelineElement parent to queue itself for
    redraw. This is not necessary though. It's enough to queue for redraw
    directly the KeyframeCurve. The parent container can handle this.
