* add QskArcNode and QskArcRenderer * IOT example: Use QskArcNode instead of own arc node * move some functionality to the arc renderer * add QskArcMetrics * add methods to QskSkinlet * remove circular bar graph node We can now use updateArcNode() and don't need our own method. * support linear gradients in the arc renderer * clean up * incorporate Uwe's changes * add overloads for updateArcNode() when the angles are set dynamically The angles don't always come from the style, so we need overloads in QskSkinlet to set them dynamically.
