  void InvertRect( LPRECT lpRect );
 
  Parameter   Description
 
  <lpRect>    Points to a ◄RECT► or ◄CRect► that contains the logical
              coordinates of the rectangle to be inverted. You can also
              pass a CRect object for this parameter.
 
  Remarks
 
  Inverts the contents of the given rectangle. On monochrome displays, the
  function makes white pixels black, and black pixels white. On color
  displays, the inversion depends on how colors are generated for the
  display. Calling InvertRect twice with the same rectangle restores the
  display to its previous colors.
 
  If the rectangle is empty, nothing is drawn.
