    NOTE ON CONTROL ACTION PROCS

    When using the TrackControl() call when tracking an indicator, the actionProc parameter

    (type ControlActionUPP) should be replaced by a parameter of type DragGrayRgnUPP

    (see Quickdraw.h).

    If, however, you are using the live feedback variants of scroll bars or sliders, you

    must pass a ControlActionUPP in when tracking the indicator as well. This functionality

    is available in Appearance 1.0 or later.
