     * @classdesc
     * Automated attribute generation and management. Suitable when a set of
     * vertex shader attributes are generated by iteration over a data array,
     * and updates to these attributes are needed either when the data itself
     * changes, or when other data relevant to the calculations change.
     *
     * - First the application registers descriptions of its dynamic vertex
     *   attributes using AttributeManager.add().
     * - Then, when any change that affects attributes is detected by the
     *   application, the app will call AttributeManager.invalidate().
     * - Finally before it renders, it calls AttributeManager.update() to
     *   ensure that attributes are automatically rebuilt if anything has been
     *   invalidated.
     *
     * The application provided update functions describe how attributes
     * should be updated from a data array and are expected to traverse
     * that data array (or iterable) and fill in the attribute's typed array.
     *
     * Note that the attribute manager intentionally does not do advanced
     * change detection, but instead makes it easy to build such detection
     * by offering the ability to "invalidate" each attribute separately.
     *
     * Summary:
     * - keeps track of valid state for each attribute
     * - auto reallocates attributes when needed
     * - auto updates attributes with registered updater functions
     * - allows overriding with application supplied buffers
     *
     * Limitations:
     * - There are currently no provisions for only invalidating a range of
     *   indices in an attribute.
