 * Changes
 * -------
 * 19-Oct-2001 : Version 1, based on code by Mark Watson (DG);
 * 22-Oct-2001 : Renamed DataSource.java --> Dataset.java etc. (DG);
 * 13-Dec-2001 : Changed return type of drawItem from void --> Shape.  The area
 *               returned can be used as the tooltip region.
 * 23-Jan-2002 : Added DrawInfo parameter to drawItem() method (DG);
 * 28-Mar-2002 : Added a property change listener mechanism.  Now renderers do
 *               not have to be immutable (DG);
 * 04-Apr-2002 : Added the initialise() method (DG);
 * 09-Apr-2002 : Removed the translated zero from the drawItem method, it can
 *               be calculated inside the initialise method if it is required.
 *               Added a new getToolTipGenerator() method.  Changed the return
 *               type for drawItem() to void (DG);
 * 24-May-2002 : Added ChartRenderingInfo the initialise method API (DG);
 * 25-Jun-2002 : Removed redundant import (DG);
 * 20-Aug-2002 : Added get/setURLGenerator methods to interface (DG);
 * 02-Oct-2002 : Fixed errors reported by Checkstyle (DG);
 * 18-Nov-2002 : Added methods for drawing grid lines (DG);
 * 17-Jan-2003 : Moved plot classes into a separate package (DG);
 * 27-Jan-2003 : Added shape lookup table (DG);
 * 05-Jun-2003 : Added domain and range grid bands (sponsored by Focus Computer
 *               Services Ltd) (DG);
 * 27-Jul-2003 : Added getRangeType() to support stacked XY area charts (RA);
 * 16-Sep-2003 : Changed ChartRenderingInfo --> PlotRenderingInfo (DG);
 * 25-Feb-2004 : Replaced CrosshairInfo with CrosshairState.  Renamed
 *               XYToolTipGenerator --> XYItemLabelGenerator (DG);
 * 26-Feb-2004 : Added lots of new methods (DG);
 * 30-Apr-2004 : Added getRangeExtent() method (DG);
 * 06-May-2004 : Added methods for controlling item label visibility (DG);
 * 13-May-2004 : Removed property change listener mechanism (DG);
 * 18-May-2004 : Added item label font and paint methods (DG);
 * 10-Sep-2004 : Removed redundant getRangeType() method (DG);
 * 06-Oct-2004 : Replaced getRangeExtent() with findRangeBounds() and added
 *               findDomainBounds (DG);
 * 23-Nov-2004 : Changed drawRangeGridLine() --> drawRangeLine() (DG);
 * 07-Jan-2005 : Removed deprecated method (DG);
 * 24-Feb-2005 : Now extends LegendItemSource (DG);
 * 20-Apr-2005 : Renamed XYLabelGenerator --> XYItemLabelGenerator (DG);
 * ------------- JFREECHART 1.0.x ---------------------------------------------
 * 19-Apr-2007 : Deprecated seriesVisible and seriesVisibleInLegend flags (DG);
 * 20-Apr-2007 : Deprecated paint, fillPaint, outlinePaint, stroke,
 *               outlineStroke, shape, itemLabelsVisible, itemLabelFont,
 *               itemLabelPaint, positiveItemLabelPosition,
 *               negativeItemLabelPosition and createEntities override
 *               fields (DG);
