* A BaseRenderTexture is a special texture that allows any Pixi display object to be rendered to it.
*
* __Hint__: All DisplayObjects (i.e. Sprites) that render to a BaseRenderTexture should be preloaded
* otherwise black rectangles will be drawn instead.
*
* A BaseRenderTexture takes a snapshot of any Display Object given to its render method. The position
* and rotation of the given Display Objects is ignored. For example:
*
* ```js
* var renderer = PIXI.autoDetectRenderer(1024, 1024, { view: canvas, ratio: 1 });
* var BaserenderTexture = new PIXI.BaseRenderTexture(renderer, 800, 600);

*
* sprite.position.x = 800/2;
* sprite.position.y = 600/2;
* sprite.anchor.x = 0.5;
* sprite.anchor.y = 0.5;
*
* BaserenderTexture.render(sprite);
* ```
*
* The Sprite in this case will be rendered to a position of 0,0. To render this sprite at its actual
* position a Container should be used:
*
* ```js
* var doc = new PIXI.Container();
*
* doc.addChild(sprite);
*
* var baseRenderTexture = new PIXI.BaserenderTexture(100, 100);
* var renderTexture = new PIXI.RenderTexture(baseRenderTexture);

* The ParticleContainer class is a really fast version of the Container built solely for speed,
* so use when you need a lot of sprites or particles. The tradeoff of the ParticleContainer is that advanced
* functionality will not work. ParticleContainer implements only the basic object transform (position, scale, rotation).
* Any other functionality like tinting, masking, etc will not work on sprites in this batch.
*
* It's extremely easy to use :
*
* ```js
* var container = new ParticleContainer();
*
* for (var i = 0; i < 100; ++i)
* {
* var sprite = new PIXI.Sprite.fromImage("myImage.png");
* container.addChild(sprite);
* }
* ```
*
* And here you have a hundred sprites that will be renderer at the speed of light.
*
