// This is a special tableau which is always the top
// of the tableau graph under each adaptor.  (Top means
// it has no parents and every tableau under the adaptor
// is a child of one of these).  Its main purpose
// is to catch messages "up" the tableau hierarchy
// like "post_redraw", and pass them on to the
// adaptor.
