/**
* Phaser - GeomSprite
*
* A GeomSprite is a special kind of GameObject that contains a base geometry class (Circle, Line, Point, Rectangle).
* They can be rendered in the game and used for collision just like any other game object. Display of them is controlled
* via the lineWidth / lineColor / fillColor and renderOutline / renderFill properties.
