Builds TreeGrid

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.

    let theme = cx.theme().clone();
    let rows = [
        ("workspace", "Workspace", 1, true, true, None),
