constructor Create( Owner: TDirectDraw; Flags: Longint );
Creates and initializes a TDirectDrawClipper instance. The Owner parameter identifies the TDirectDraw object that will create this instance of TDirectDrawClipper. You can set Owner to nil to create an independent clipper but you need version 2, or later, of DirectX to be installed. See IDirectDraw2::CreateClipper and DirectDrawCreateClipper for more information.
