* IOT example, circular progress bar: Use a pen instead of a brush That way we don't have to draw two circles, and we can in addition use a conical gradient. * IOT example: Make circular progress bar a QskControl ... and internally use a QskPaintedNode for now. By doing this we already have the API ready (similar to QskProgressBar) and can swap the QskPaintedNode with an arc renderer at a later point in time.
