     *     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 {HTMLCanvasElement} [options.view] - The canvas to use as a view, optional.
     * @param {boolean} [options.useContextAlpha=true] - Pass-through value for canvas' context `alpha` property.
     *   If you want to set transparency, please use `backgroundAlpha`. This option is for cases where the
     *   canvas needs to be opaque, possibly for performance reasons on some older devices.
     * @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
     * @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=PIXI.settings.RESOLUTION] - The resolution / device pixel ratio of the renderer.
     * @param {boolean} [options.forceCanvas=false] - prevents selection of WebGL renderer, even if such is present, this
     *   option only is available when using **pixi.js-legacy** or **@pixi/canvas-renderer** modules, otherwise
     *   it is ignored.
     * @param {number} [options.backgroundColor=0x000000] - The background color of the rendered area
     *  (shown if not transparent).
     * @param {number} [options.backgroundAlpha=1] - Value from 0 (fully transparent) to 1 (fully opaque).
     * @param {boolean} [options.clearBeforeRender=true] - This sets if the renderer will clear the canvas or
     *   not before the new render pass.
     * @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.
     *  If set to false, you cannot register a handler to occur before anything that runs on the shared ticker.
     *  The system ticker will always run before both the shared ticker and the app ticker.
     * @param {boolean} [options.sharedLoader=false] - `true` to use PIXI.Loader.shared, `false` to create new Loader.
     * @param {Window|HTMLElement} [options.resizeTo] - Element to automatically resize stage to.
