// Declares the VideoSource class
// 
// This is a very simple class to provide video input; this can be
// replaced with whatever form of video input that is needed.  It
// should open the video input on construction, and provide two
// function calls after construction: Size() must return the video
// format as an ImageRef, and GetAndFillFrameBWandRGB should wait for
// a new frame and then overwrite the passed-as-reference images with
// GreyScale and Colour versions of the new frame.
