Hey pixi peeps!   Good news I just added the SpriteBatch class to the pixi.js dev branch!   See it in action here: http://www.goodboydigital.com/pixijs/bunnymark/   For all intents and purposes it’s basically a turbo-charged displayObjectContainer.  You add sprites to it as you normally would and it will render them really fast.  This container type is especially useful for when you want to render tonnes of sprites per frame. You know like particles / bullets / tilemaps or er… bunnies? In sweat
