// CLASS:	YUVFileParams
//
// PURPOSE:	This class is designed to hold the parameters required to
//		read a YUV video file.  Such parameters include things
//		like the frame height and width, but they also include
//		things like the buffer offsets required to properly
//		read an image into a PicBuffer object as the JSVM code
//		seems to expect.
//
// MODIFIED:	Tue Mar 14, 2006 (EM) Created initial version.
