 *
 * Changes
 * -------
 * 05-Aug-2003 : Version 1, contributed by David Browning.  Based on code in the
 *               CandlestickRenderer class.  Additional modifications by David
 *               Gilbert to make the code work with 0.9.10 changes (DG);
 * 08-Aug-2003 : Updated some of the Javadoc
 *               Allowed BoxAndwhiskerDataset Average value to be null - the
 *               average value is an AIMS requirement
 *               Allow the outlier and farout coefficients to be set - though
 *               at the moment this only affects the calculation of farouts.
 *               Added artifactPaint variable and setter/getter
 * 12-Aug-2003   Rewrote code to sort out and process outliers to take
 *               advantage of changes in DefaultBoxAndWhiskerDataset
 *               Added a limit of 10% for width of box should no width be
 *               specified...maybe this should be setable???
 * 20-Aug-2003 : Implemented Cloneable and PublicCloneable (DG);
 * 08-Sep-2003 : Changed ValueAxis API (DG);
 * 16-Sep-2003 : Changed ChartRenderingInfo --> PlotRenderingInfo (DG);
 * 25-Feb-2004 : Replaced CrosshairInfo with CrosshairState (DG);
 * 23-Apr-2004 : Added fillBox attribute, extended equals() method and fixed
 *               serialization issue (DG);
 * 29-Apr-2004 : Fixed problem with drawing upper and lower shadows - bug id
 *               944011 (DG);
 * 15-Jul-2004 : Switched getX() with getXValue() and getY() with
 *               getYValue() (DG);
 * 01-Oct-2004 : Renamed 'paint' --> 'boxPaint' to avoid conflict with
 *               inherited attribute (DG);
 * 10-Jun-2005 : Updated equals() to handle GradientPaint (DG);
 * 06-Oct-2005 : Removed setPaint() call in drawItem(), it is causing a
 *               loop (DG);
 * ------------- JFREECHART 1.0.x ---------------------------------------------
 * 02-Feb-2007 : Removed author tags from all over JFreeChart sources (DG);
 * 05-Feb-2007 : Added event notifications and fixed drawing for horizontal
 *               plot orientation (DG);
 * 13-Jun-2007 : Replaced deprecated method call (DG);
 * 03-Jan-2008 : Check visibility of average marker before drawing it (DG);
 * 27-Mar-2008 : If boxPaint is null, revert to itemPaint (DG);
 * 27-Mar-2009 : Added findRangeBounds() method override (DG);
 *
