 *   The AtAxisCore class is the parent placeholder for for all Axis
 *   classes.  It handles maintaing and calling the callback lists, and
 *   knows how to draw the axis and labels from the stuff stored in the
 *   private part of the record.  It has no recalc proceedure so
 *   actually setting up these arrays has to be done by subclasses.
 *
 *   The range and position functions can be chained from subclass range
 *   and position functions.
