Hmm... I'm not sure what CtlGetValue or CtlGetSliderValues *should* do.
When you're dragging, the new slider value isn't 'true' yet. e.g. you can
drag vertically outside the bounds and the slider snaps back to the old
value...
Anyway, the new (intermediate) value is passed as part of the
ctlRepeatEvent! It's in event.data.ctlRepeat.value
Clearly you can update the intermediate value while the slider is being
dragged, as both the contrast (Palm V) and brightness (Palm IIIc) controls
update while you're dragging. :-) (In fact, it's those UI elements that
prompted the addition of the slider control to the API!)
