/**
* 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.
