@param {String} [config.fill] fill color
     * @param {Image} [config.fillPatternImage] fill pattern image
     * @param {Number} [config.fillPatternX]
     * @param {Number} [config.fillPatternY]
     * @param {Object} [config.fillPatternOffset] object with x and y component
     * @param {Number} [config.fillPatternOffsetX] 
     * @param {Number} [config.fillPatternOffsetY] 
     * @param {Object} [config.fillPatternScale] object with x and y component
     * @param {Number} [config.fillPatternScaleX]
     * @param {Number} [config.fillPatternScaleY]
     * @param {Number} [config.fillPatternRotation]
     * @param {String} [config.fillPatternRepeat] can be "repeat", "repeat-x", "repeat-y", or "no-repeat".  The default is "no-repeat"
     * @param {Object} [config.fillLinearGradientStartPoint] object with x and y component
     * @param {Number} [config.fillLinearGradientStartPointX]
     * @param {Number} [config.fillLinearGradientStartPointY]
     * @param {Object} [config.fillLinearGradientEndPoint] object with x and y component
     * @param {Number} [config.fillLinearGradientEndPointX]
     * @param {Number} [config.fillLinearGradientEndPointY]
     * @param {Array} [config.fillLinearGradientColorStops] array of color stops
     * @param {Object} [config.fillRadialGradientStartPoint] object with x and y component
     * @param {Number} [config.fillRadialGradientStartPointX]
     * @param {Number} [config.fillRadialGradientStartPointY]
     * @param {Object} [config.fillRadialGradientEndPoint] object with x and y component
     * @param {Number} [config.fillRadialGradientEndPointX] 
     * @param {Number} [config.fillRadialGradientEndPointY] 
     * @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.fillAfterStrokeEnabled]. Should we draw fill AFTER stroke? Default is false.
     * @param {Number} [config.hitStrokeWidth] size of the stroke on hit canvas.  The default is "auto" - equals to strokeWidth
     * @param {Boolean} [config.strokeHitEnabled] flag which enables or disables stroke hit region.  The default is true
     * @param {Boolean} [config.perfectDrawEnabled] flag which enables or disables using buffer canvas.  The default is true
     * @param {Boolean} [config.shadowForStrokeEnabled] flag which enables or disables shadow for stroke.  The default is true
     * @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 square.  The default
     *  is butt
     * @param {String} [config.shadowColor]
     * @param {Number} [config.shadowBlur]
     * @param {Object} [config.shadowOffset] object with x and y component
     * @param {Number} [config.shadowOffsetX]
     * @param {Number} [config.shadowOffsetY]
     * @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.dash]
     * @param {Boolean} [config.dashEnabled] flag which enables or disables the dashArray.  The default value is true
