    Timeline: Optimize selection tools for fewer scene graph rebuilds · 21a94e5e
    Ulf Hermann authored
    The selection details "windows" contain frequently updated text and can
    be moved around in the scene. We don't want their contents to be batched
    with the rest of the scene as there may be many events in the timeline
    and rebuilding the batch they are in is expensive. The clip property has
    the side effect of preventing nodes within the clipped area from getting
    batched with nodes outside it. Thus, by setting the clip property on
    the details we reduce the number of batch rebuilds for the actual
    timeline.
    
    Having a transparent rectangle in there doesn't help the renderer,
    either, so we replace it with a plain item.
