{
 *  Discussion:
 *    There are several variants that control the behavior of the
 *    slider control. Any combination of the following three constants
 *    can be added to the basic CDEF ID (kSliderProc). 
 *    
 *    Mac OS X has a "Scroll to here" option in the General pane of
 *    System Preferences which allows users to click in the page
 *    up/down regions of a slider and have the thumb/indicator jump
 *    directly to the clicked position, which alters the value of the
 *    slider and moves any associated content appropriately. As long as
 *    the mouse button is held down, the click is treated as though the
 *    user had clicked in the thumb/indicator in the first place.
 *    
 *    
 *    If you want the sliders in your application to work with the
 *    "Scroll to here" option, you must do the following: 
 *    
 *    1. Create live-tracking sliders, not sliders that show a "ghost"
 *    thumb when you click on it. You can request live-tracking sliders
 *    by passing true in the liveTracking parameter to
 *    CreateSliderControl. If you create sliders with NewControl, use
 *    the kControlSliderLiveFeedback variant. 
 *    
 *    2. Write an appropriate ControlActionProc and associate it with
 *    your slider via the SetControlAction API. This allows your
 *    application to update its content appropriately when the
 *    live-tracking slider is clicked. 
 *    
 *    3. When calling HandleControlClick or TrackControl, pass -1 in
 *    the action proc parameter. This is a request for the Control
 *    Manager to use the action proc you associated with your control
 *    in step 2. If you rely on the standard window event handler to do
 *    your control tracking, this step is handled for you automatically.
