 *  History:
 *   Date	By	Reason
 *   ====	==	======
 *   06-jan-95	craige	initial implementation
 *   03-mar-95	craige	added dprintf2
 *   31-mar-95	craige	add DPFInit to read WIN.INI for [DirectDraw] section;
 *			added dprintf3
 *   01-apr-95	craige	happy fun joy updated header file
 *   06-apr-95	craige	made stand-alone
 *   18-jun-95	craige	use negative dpf level to display ONLY that level
 *   06-dec-95  jeffno  Changed dprintf to use c-standard variable argument
 *                      list techniques. Also added abs for NT
 *   06-feb-96  colinmc added simple assertion mechanism for DirectDraw
 *   15-apr-96	kipo	added msinternal
