 Usage Notes
   ■ The three-dimensional (3D) effect applies only to controls with borders
     around them.
 
   ■ A form containing 3D controls becomes, in effect, a 3D form. However,
     the THREE_D constant has no effect on a form's border.
 
   ■ When THREE_D is set to True (-1), half of the control border is drawn
     in black, and the other half is drawn in the same color, but opposite
     intensity of the control's background.
 
   ■ When THREE_D is set to False (0), control borders are drawn in the
     foreground color of the control.
 
   ■ Command buttons have the black border along the bottom and right edges,
     thus producing a "raised" look. All other framed controls have the
     black border along the top and left edges, producing an "sunken" look.
 
   ■ The type of control and its BackColor property setting determine the
     border color when the 3D display is in effect:
