  *      History:  
  *  
  *      12.07.2002      num_threads  
  *      23.06.2002      XVID_CPU_CHKONLY; loading speed up  
  *      25.04.2002      ICDECOMPRESS_PREROLL  
  *      17.04.2002      re-enabled lumi masking for 1st pass  
  *      15.04.2002      updated cbr support  
  *      04.04.2002      separated 2-pass code to 2pass.c  
  *                              interlacing support  
  *                              hinted ME support  
  *      23.03.2002      daniel smith <danielsmith@astroboymail.com>  
  *                              changed inter4v to only be in modes 5 or 6  
  *                              fixed null mode crash ?  
  *                              merged foxer's alternative 2-pass code  
  *                              added DEBUGERR output on errors instead of returning  
  *      16.03.2002      daniel smith <danielsmith@astroboymail.com>  
  *                              changed BITMAPV4HEADER to BITMAPINFOHEADER  
  *                                      - prevents memcpy crash in compress_get_format()  
  *                              credits are processed in external 2pass mode  
  *                              motion search precision = 0 now effective in 2-pass  
  *                              modulated quantization  
  *                              added DX50 fourcc  
  *      01.12.2001      inital version; (c)2001 peter ross <pross@xvid.org>
