// Created : 22nd August 1996
// By : P.R.Porter
//
// Version Date By Description
// ------- --------- --- -----------------------------------------------
// 1.0 16-Sep-96 PRP Interface to the DirectDraw driver functions
// and data.
//
// 1.1 19-Sep-96 PRP Increased scope of directDraw data, such as
// the back buffer object, so that mouse.c can
// have access to the screen.
//
// 1.2 25-Sep-96 PRP Made scrollx and scrolly available to all
// driver code.
//
// 1.3 26-Sep-96 PRP Moved scroll stuff to render.h for clarity.
//
// 1.4 07-Nov-96 PRP Made bFullScreen available to all driver code.
//
// 1.5 18-Nov-96 PRP Added reference to lpDD2 object.
//
// 1.6 24-Jan-97 PRP Added hardware capability bits and defines.
//
// 1.7 06-Mar-97 PRP Changed capability bits, and changed the
// direct draw error reporting call. Added
// function to grab screen shot.
//
// 1.8 16-Jun-97 PSJ Made globall externable to c++.
//
// 1.9 27-Jun-97 PRP Moving the definition of GrabScreenShot to
// driver96.h for external access.
//
//
// Summary : This include file defines links to all data which is
// defined in the d_draw.c module, but can be accessed by
// other parts of the driver96 library.
