  /**
   * When you call methods like for example {@link #setHalfWidth(float)} or {@link
   * #updateVertex(int, float, float)} work is being queued up. Before each draw call this method is
   * automatically called to do all this work.
   *
   * <p>It can be smart to call this method after you are done configuring your OutlinePolygon, but
   * before you exit your loading screen. This way you do more work during the loading screen and
   * get less initial lag.
