@param {String} [config.fill] fill color
     * @param {Image} [config.fillPatternImage] fill pattern image
     * @param {Number} [config.fillPatternX]
     * @param {Number} [config.fillPatternY]
     * @param {Array|Object} [config.fillPatternOffset] array with two elements or object with x and y component
     * @param {Array|Object} [config.fillPatternScale] array with two elements or object with x and y component
     * @param {Number} [config.fillPatternRotation]
     * @param {String} [config.fillPatternRepeat] can be 'repeat', 'repeat-x', 'repeat-y', or 'no-repeat'.  The default is 'no-repeat'
     * @param {Array|Object} [config.fillLinearGradientStartPoint] array with two elements or object with x and y component
     * @param {Array|Object} [config.fillLinearGradientEndPoint] array with two elements or object with x and y component
     * @param {Array} [config.fillLinearGradientColorStops] array of color stops
     * @param {Array|Object} [config.fillRadialGradientStartPoint] array with two elements or object with x and y component
     * @param {Array|Object} [config.fillRadialGradientEndPoint] array with two elements or object with x and y component
     * @param {Number} [config.fillRadialGradientStartRadius]
     * @param {Number} [config.fillRadialGradientEndRadius]
     * @param {Array} [config.fillRadialGradientColorStops] array of color stops
     * @param {Boolean} [config.fillEnabled] flag which enables or disables the fill.  The default value is true
     * @param {String} [config.fillPriority] can be color, linear-gradient, radial-graident, or pattern.  The default value is color.  The fillPriority property makes it really easy to toggle between different fill types.  For example, if you want to toggle between a fill color style and a fill pattern style, simply set the fill property and the fillPattern properties, and then use setFillPriority('color') to render the shape with a color fill, or use setFillPriority('pattern') to render the shape with the pattern fill configuration
     * @param {String} [config.stroke] stroke color
     * @param {Number} [config.strokeWidth] stroke width
     * @param {Boolean} [config.strokeScaleEnabled] flag which enables or disables stroke scale.  The default is true
     * @param {Boolean} [config.strokeEnabled] flag which enables or disables the stroke.  The default value is true
     * @param {String} [config.lineJoin] can be miter, round, or bevel.  The default
     *  is miter
     * @param {String} [config.lineCap] can be butt, round, or sqare.  The default
     *  is butt
     * @param {String} [config.shadowColor]
     * @param {Number} [config.shadowBlur]
     * @param {Obect} [config.shadowOffset]
     * @param {Number} [config.shadowOffset.x]
     * @param {Number} [config.shadowOffset.y]
     * @param {Number} [config.shadowOpacity] shadow opacity.  Can be any real number
     *  between 0 and 1
     * @param {Boolean} [config.shadowEnabled] flag which enables or disables the shadow.  The default value is true
     * @param {Array} [config.dashArray]
     * @param {Boolean} [config.dashArrayEnabled] flag which enables or disables the dashArray.  The default value is true
