\class SliderControl SliderControl.h "vcf/ApplicationKit/SliderControl.h"
The SliderControl, sometimes referred to as a "trackbar" provides
a UI that consists of a thumb button that slides, vertically or
horizontally, along a "track". Sliding this causes the position 
value to change. The position is bounded by a minimum and maximum
value.
