// TGSpeedo //
// //
// TGSpeedo is a widget looking like a speedometer, with a needle, //
// a counter and a small odometer window. //
// //
// Three thresholds are configurable, with their glowing color //
// A peak mark can be enabled, allowing to keep track of the highest //
// value displayed. The mark can be reset by right-clicking on the //
// widget. //
// Two signals are available: //
// OdoClicked(): when user click on the small odometer window //
// LedClicked(): when user click on the small led near the counter //
// //
