10 * A slider control.  Contains a "knob" object, which slides along a "track" object.
11 * Both the track and the knob are supplied at object creation time, and the slider
12 * adjusts its contentSize according to the knob and track's size as well as their scale factor. <br>
13 * This means that you can prescale the knob and/or track and still have a functioning slider.
