  12/1/93 Mike Duke Original module started as start for NT version of QRY
		    library.

   $0006
      miked: 2/17/1994
	removed member ulRcSize from VIDEO_CHIP_INFO

   $0004
      miked: 1/26/1994
	 Added member ulRcSize to VIDEO_CHIP_INFO for getting the resource
	 size from the registry.  Also revved the VIDEO_CHIP_INFO_VERSION
