//*************************************************************************
//  MODULE : Gfx - Module function prototypes                             *
//  AUTHOR : Ron Chernich                                                 *
//  PURPOSE: This module contains all the compiler dependant primitive    *
//           graphic functions required by the RCOS system.  These names  *
//           are invariant - the underlying code willbe compiler specific *     for graphic     graphic
//  HISTORY:                                                              *
//   02-DEC-92  First (MSC/C++ 7.00) version                              *
//   24-JAN-93	Clipping routines added 				  *
//   09-APR-93	Borland GfxTextHeight simplified, removing parameter	  * 
//   01-FEB-94  All int params changed to typedef'ed types.               *
//   05-FEB-94  GfxFill and GfxImageSize functions removed                *
