Iot dashboard arc rendering (#134) * 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.

#ifndef QSK_ARC_NODE_H
#define QSK_ARC_NODE_H
QskArcNode is a QskShapeNode now. The performance of the previous implementation was simply horrible, when drawing an arc with a small span angle. The size of the corresponding full circle is huge and the previous implementation always created an image/texture with that size. However the final implementation is supposed to create vertex lists - like what the box renderer does. So this code will also not stay forever.
