       *     **Note**: Setting this parameter to false does NOT stop the shared ticker even if you set
       *     options.sharedTicker to true in case that it is already started. Stop it by your own.
       * @param {number} [options.width=800] - The width of the renderers view.

       * @param {boolean} [options.transparent=false] - If the render view is transparent.
       * @param {boolean} [options.autoDensity=false] - Resizes renderer view in CSS pixels to allow for
       *   resolutions other than 1.
       * @param {boolean} [options.antialias=false] - Sets antialias (only applicable in Chrome at the moment).
       * @param {boolean} [options.preserveDrawingBuffer=false] - Enables drawing buffer preservation, enable this if you
       *  need to call toDataUrl on the WebGL context.
       * @param {number} [options.resolution=1] - The resolution / device pixel ratio of the renderer, retina would be 2.
       * @param {boolean} [options.forceCanvas=false] - Prevents selection of WebGL renderer, even if such is present.
       * @param {number} [options.backgroundColor=0x000000] - The background color of the rendered area
       *  (shown if not transparent).
       * @param {boolean} [options.clearBeforeRender=true] - This sets if the renderer will clear the canvas or
       *   not before the new render pass.
       * @param {boolean} [options.forceFXAA=false] - Forces FXAA antialiasing to be used over native.
       *  FXAA is faster, but may not always look as great. **(WebGL only)**.
       * @param {string} [options.powerPreference] - Parameter passed to webgl context, set to "high-performance"
       *  for devices with dual graphics card. **(WebGL only)**.
       * @param {boolean} [options.sharedTicker=false] - `true` to use PIXI.Ticker.shared, `false` to create new ticker.
       * @param {boolean} [options.sharedLoader=false] - `true` to use PIXI.Loaders.shared, `false` to create new Loader.
       * @param {Window|HTMLElement} [options.resizeTo] - Element to automatically resize stage to.
