The code that drew it

A still frame holds a repeating animation at its first frame and a one-shot at its last, because a still of a moving thing is not reproducible. Run the gallery to review motion.

fn undo_history(_window: &mut Window, cx: &mut App) -> AnyElement {
    let theme = cx.theme().clone();
    stack(&theme)
        .w(px(520.0))
        .child(caption(
            &theme,
            "the caller owns every revision and whether it can be restored",
        ))
        .child(
            UndoHistory::new("scene.undo-history", "Document undo history")
                .entries([
