     *  **WebGL Only.** Whether to enable anti-aliasing. This may affect performance.
     * @param {boolean} [options.autoDensity=false] -
     *  Whether the CSS dimensions of the renderer's view should be resized automatically.
     * @param {boolean} [options.autoStart=true] - Automatically starts the rendering after the construction.
     *  **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.backgroundAlpha=1] -
     *  Transparency of the background color, value from `0` (fully transparent) to `1` (fully opaque).
     * @param {number} [options.backgroundColor=0x000000] -
     *  The background color used to clear the canvas. It accepts hex numbers (e.g. `0xff0000`).
     * @param {boolean} [options.clearBeforeRender=true] - Whether to clear the canvas before new render passes.
     * @param {PIXI.IRenderingContext} [options.context] - **WebGL Only.** User-provided WebGL rendering context object.
     * @param {boolean} [options.forceCanvas=false] -
     *  Force using {@link PIXI.CanvasRenderer}, even if WebGL is available. This option only is available when
     *  using **pixi.js-legacy** or **@pixi/canvas-renderer** packages, otherwise it is ignored.
     * @param {number} [options.height=600] - The height of the renderer's view.
     * @param {string} [options.powerPreference] -
     *  **WebGL Only.** A hint indicating what configuration of GPU is suitable for the WebGL context,
     *  can be `'default'`, `'high-performance'` or `'low-power'`.
     *  Setting to `'high-performance'` will prioritize rendering performance over power consumption,
     *  while setting to `'low-power'` will prioritize power saving over rendering performance.
     * @param {boolean} [options.premultipliedAlpha=true] -
     *  **WebGL Only.** Whether the compositor will assume the drawing buffer contains colors with premultiplied alpha.
     * @param {boolean} [options.preserveDrawingBuffer=false] -
     *  **WebGL Only.** Whether to enable drawing buffer preservation. If enabled, the drawing buffer will preserve
     *  its value until cleared or overwritten. Enable this if you need to call `toDataUrl` on the WebGL context.
     * @param {Window|HTMLElement} [options.resizeTo] - Element to automatically resize stage to.
     * @param {number} [options.resolution=PIXI.settings.RESOLUTION] -
     *  The resolution / device pixel ratio of the renderer.
     * @param {boolean} [options.sharedLoader=false] - `true` to use PIXI.Loader.shared, `false` to create new Loader.
     * @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.transparent] -
     *  **Deprecated since 6.0.0, Use `backgroundAlpha` instead.** \
     *  `true` sets `backgroundAlpha` to `0`, `false` sets `backgroundAlpha` to `1`.
     * @param {boolean|'notMultiplied'} [options.useContextAlpha=true] -
     *  Pass-through value for canvas' context attribute `alpha`. This option is for cases where the
     *  canvas needs to be opaque, possibly for performance reasons on some older devices.
     *  If you want to set transparency, please use `backgroundAlpha`. \
     *  **WebGL Only:** When set to `'notMultiplied'`, the canvas' context attribute `alpha` will be
     *  set to `true` and `premultipliedAlpha` will be to `false`.
     * @param {HTMLCanvasElement} [options.view=null] -
     *  The canvas to use as the view. If omitted, a new canvas will be created.
     * @param {number} [options.width=800] - The width of the renderer's view.
