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
