   * The SVGElement prototype is a JavaScript wrapper for SVG elements used in the

   * object, these prototypes allow freeform annotation in the charts or even in
   * HTML pages without instanciating a chart. The SVGElement can also wrap HTML
   * labels, when `text` or `label` elements are created with the `useHTML`
   * parameter.
   *
   * The SVGElement instances are created through factory functions on the
   * {@link Highcharts.SVGRenderer}
   * object, like
   * {@link Highcharts.SVGRenderer#rect|rect},
   * {@link Highcharts.SVGRenderer#path|path},
