   * 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
   * let renderer = PIXI.autoDetectRenderer(1024, 1024);
   * let baseRenderTexture = new PIXI.BaseRenderTexture(800, 600);

   * sprite.anchor.y = 0.5;
   *
   * renderer.render(sprite, renderTexture);
   * ```
   *
   * The Sprite in this case will be rendered using its local transform. To render this sprite at 0,0
   * you can clear the transform
   *
   * ```js
   *
   * sprite.setTransform()
   *
   * let baseRenderTexture = new PIXI.BaseRenderTexture(100, 100);
