    /// Starting from this size, the layout will tighten its grip on the children,
    /// slowly allocating less and less of the available size up to the maximum
    /// allocated size. Below that threshold and below the maximum size, the
    /// children will be allocated all the available size.
    ///
    /// If the threshold is greater than the maximum size to allocate to the
    /// children, they will be allocated the whole size up to the maximum. If the
    /// threshold is lower than the minimum size to allocate to the children, that
    /// size will be used as the tightening threshold.

    /// Effectively, tightening the grip on a child before it reaches its maximum
    /// size makes transitions to and from the maximum size smoother when resizing.
