24   *  05.10.2002  support for interpolated images in qpel mode - Isibaar   ****************************************************************************/
  *      01.05.2002      BFRAME image-based u,v interpolation  
  *  22.04.2002  added some B-frame support  
  *      14.04.2002      added image_dump_yuvpgm(), added image_mad()  
  *              XVID_CSP_USER input support  
  *  09.04.2002  PSNR calculations - Isibaar  
  *      06.04.2002      removed interlaced edging from U,V blocks (as per spec)  
  *  26.03.2002  interlacing support (field-based edging in set_edges)  
  *      26.01.2002      rgb555, rgb565  
  *      07.01.2001      commented u,v interpolation (not required for uv-block-based)  
  *  23.12.2001  removed #ifdefs, added function pointers + init_common()  
  *      22.12.2001      cpu #ifdefs  
  *  19.12.2001  image_dump(); useful for debugging  
  *       6.12.2001      inital version; (c)2001 peter ross <pross@cs.rmit.edu.au>
