;//    Rev 1.11   25 Sep 1996 08:05:36   KLILLEVO
;// initial extended motion vectors support 
;// does not work for AP yet
;// 
;//    Rev 1.10   09 Jul 1996 16:47:26   AGUPTA2
;// MMX_ClipAndMove now addas DC value to the result; IDCT for INTRA blocks
;// works with DC value set to zero.  Also, BlockCopy is done in chunks of
;// 4 loads followed by 4 stores.
;// Changed code to adhere to coding convention in the decoder.
;// 
;//    Rev 1.9   04 Apr 1996 11:05:56   AGUPTA2
;// Added decl for MMX_BlockCopy().
;// 
;//    Rev 1.8   14 Mar 1996 17:03:10   AGUPTA2
;// Added decls for MMX rtns.
;// 
;//    Rev 1.7   08 Mar 1996 16:46:24   AGUPTA2
;// Changed function declarations.
;// 
;// 
;//    Rev 1.6   23 Feb 1996 09:46:50   KLILLEVO
;// fixed decoding of Unrestricted Motion Vector mode
;// 
;//    Rev 1.5   18 Dec 1995 12:47:52   RMCKENZX
