Assumptions are evil.
I haven't done this with a slider, but I wouldn't assume they have to be
drawn separately. Well, yes, *you* need to draw them separately, but in the
same kEventControlDraw event. It wouldn't make sense to get separate events
for the track and the indicator.
Don't assume. Just draw it the way you want in the kEventControlDraw.
