     * the browser then this function will return a canvas renderer
     *
     * @memberof PIXI
     * @param width=800 {number} the width of the renderers view
     * @param height=600 {number} the height of the renderers view
     * @param [options] {object} The optional renderer parameters
     * @param [options.view] {HTMLCanvasElement} the canvas to use as a view, optional
     * @param [options.transparent=false] {boolean} If the render view is transparent, default false
     * @param [options.antialias=false] {boolean} sets antialias (only applicable in chrome at the moment)
     * @param [options.preserveDrawingBuffer=false] {boolean} enables drawing buffer preservation, enable this if you
     *      need to call toDataUrl on the webgl context
     * @param [options.resolution=1] {number} the resolution of the renderer, retina would be 2
     * @param [noWebGL=false] {boolean} prevents selection of WebGL renderer, even if such is present
     *
     * @return {WebGLRenderer|CanvasRenderer} Returns WebGL renderer if available, otherwise CanvasRenderer
