 * 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.
