/**
 * The shared ticker instance used by {@link PIXI.extras.MovieClip}.
 * and by {@link PIXI.interaction.InteractionManager}.
 * The property {@link PIXI.ticker.Ticker#autoStart} is set to `true`
 * for this instance. Please follow the examples for usage, including
 * how to opt-out of auto-starting the shared ticker.
 *
 * @example
 *     var ticker = PIXI.ticker.shared;
 *     // Set this to prevent starting this ticker when listeners are added.
 *     // By default this is true only for the PIXI.ticker.shared instance.
 *     ticker.autoStart = false;
 *     // FYI, call this to ensure the ticker is stopped. It should be stopped
 *     // if you have not attempted to render anything yet.
 *     ticker.stop();
 *     // Call this when you are ready for a running shared ticker.
 *     ticker.start();
 *
 * @example
 *     // You may use the shared ticker to render...
 *     var renderer = PIXI.autoDetectRenderer(800, 600);
 *     var stage = new PIXI.Container();
 *     var interactionManager = PIXI.interaction.InteractionManager(renderer);
 *     document.body.appendChild(renderer.view);
 *     ticker.add(function (time) {
 *         renderer.render(stage);
 *     });
 *
 * @example
 *     // Or you can just update it manually.
 *     ticker.autoStart = false;
 *     ticker.stop();
 *     function animate(time) {
 *         ticker.update(time);
 *         renderer.render(stage);
 *         requestAnimationFrame(animate);
 *     }
 *     animate(performance.now());
 *
 * @type {PIXI.ticker.Ticker}
