	 * A Shape allows you to display vector art in the display list. It composites a {{#crossLink "Graphics"}}{{/crossLink}}
	 * instance which exposes all of the vector drawing methods. The Graphics instance can be shared between multiple Shape
	 * instances to display the same vector graphics with different positions or transforms.
	 *
	 * If the vector art will not
	 * change between draws, you may want to use the {{#crossLink "DisplayObject/cache"}}{{/crossLink}} method to reduce the
	 * rendering cost.
