 *  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
