//  Here's our ControlActionUPP that also handles the indicator. At last, we can

//  actually use the same function callback for both! There is a difference when

//  called with the indicator as the part, as opposed to the up/down arrows, etc.

//  If we are called because the indicator is being dragged, the value has already

//  been calculated for us. If we are being called because the scroll bar arrows

//  have been pressed, then we must determine how much to scroll by and set the

//  scroll bar value accordingly. This allows us to have control over the amount

//  that arrows scroll by. We can allow the indicator dragging to determine the

//  value because the indicator always shows a percentage.
