Draw1Control
Draw1Control Draw a single control [128K ROMs]
#include <Controls.h> Control Manager
void Draw1Control(theControl );
ControlHandle theControl ; handle leading to control to draw
Draw1Control draws a single control in the active window, if it is active
and visible.
theControl is a handle leading to a variable-length ControlRecord structure. It
specifies which control to draw.
Returns: none

Notes: Draw1Control is available on the 128K and later versions of the ROMs.
As with UpdtControl, it is more efficient to draw only the controls that
need updating.
Use DrawControls to draw all controls in a window.
