Constant descriptions

kDrawControlEntireControl: Draw the entire control.
kDrawControlIndicatorOnly: Draw the indicator only.

The Control Manager passes one of these drawing constants in the low word of the param parameter to specify whether the user is drawing an indicator or the whole control. The high-order word of the param parameter may contain undefined data; therefore, evaluate only the low-order word of this parameter.
