038     * Changes
039     * -------
040     * 19-Oct-2001 : Version 1, based on code by Mark Watson (DG);
041     * 22-Oct-2001 : Renamed DataSource.java --> Dataset.java etc. (DG);
042     * 13-Dec-2001 : Changed return type of drawItem from void --> Shape.  The area
043     *               returned can be used as the tooltip region.
044     * 23-Jan-2002 : Added DrawInfo parameter to drawItem() method (DG);
045     * 28-Mar-2002 : Added a property change listener mechanism.  Now renderers do 
046     *               not have to be immutable (DG);
047     * 04-Apr-2002 : Added the initialise() method (DG);
048     * 09-Apr-2002 : Removed the translated zero from the drawItem method, it can 
049     *               be calculated inside the initialise method if it is required.
050     *               Added a new getToolTipGenerator() method.  Changed the return 
051     *               type for drawItem() to void (DG);
052     * 24-May-2002 : Added ChartRenderingInfo the initialise method API (DG);
053     * 25-Jun-2002 : Removed redundant import (DG);
054     * 20-Aug-2002 : Added get/setURLGenerator methods to interface (DG);
055     * 02-Oct-2002 : Fixed errors reported by Checkstyle (DG);
056     * 18-Nov-2002 : Added methods for drawing grid lines (DG);
057     * 17-Jan-2003 : Moved plot classes into a separate package (DG);
058     * 27-Jan-2003 : Added shape lookup table (DG);
059     * 05-Jun-2003 : Added domain and range grid bands (sponsored by Focus Computer
060     *               Services Ltd) (DG);
061     * 27-Jul-2003 : Added getRangeType() to support stacked XY area charts (RA);
062     * 16-Sep-2003 : Changed ChartRenderingInfo --> PlotRenderingInfo (DG);
063     * 25-Feb-2004 : Replaced CrosshairInfo with CrosshairState.  Renamed 
064     *               XYToolTipGenerator --> XYItemLabelGenerator (DG);
065     * 26-Feb-2004 : Added lots of new methods (DG);
066     * 30-Apr-2004 : Added getRangeExtent() method (DG);
067     * 06-May-2004 : Added methods for controlling item label visibility (DG);
068     * 13-May-2004 : Removed property change listener mechanism (DG);
069     * 18-May-2004 : Added item label font and paint methods (DG);
070     * 10-Sep-2004 : Removed redundant getRangeType() method (DG);
071     * 06-Oct-2004 : Replaced getRangeExtent() with findRangeBounds() and added 
072     *               findDomainBounds (DG);
073     * 23-Nov-2004 : Changed drawRangeGridLine() --> drawRangeLine() (DG);
074     * 07-Jan-2005 : Removed deprecated method (DG);
075     * 24-Feb-2005 : Now extends LegendItemSource (DG);
076     * 20-Apr-2005 : Renamed XYLabelGenerator --> XYItemLabelGenerator (DG);
077     * ------------- JFREECHART 1.0.x ---------------------------------------------
078     * 19-Apr-2007 : Deprecated seriesVisible and seriesVisibleInLegend flags (DG);
079     * 20-Apr-2007 : Deprecated paint, fillPaint, outlinePaint, stroke, 
080     *               outlineStroke, shape, itemLabelsVisible, itemLabelFont, 
081     *               itemLabelPaint, positiveItemLabelPosition, 
082     *               negativeItemLabelPosition and createEntities override 
083     *               fields (DG);
