* Speedometer: Inherit from QskRangeControl We don't need start/endAngle() etc. and value() anymore, but can use the methods from QskRangeControl. * Speedometer: Make it skinnable * automotive example: Only use two specially created skins ... because the default skins do not have hints for e.g. the speedometer. Also, display the speedometer page by default.
