     * Class: $.jqplot.DonutRenderer
     * Plugin renderer to draw a donut chart.
     * x values, if present, will be used as slice labels.
     * y values give slice size.
     * 
     * To use this renderer, you need to include the 
     * donut renderer plugin, for example:
     * 
     * > <script type="text/javascript" src="plugins/jqplot.donutRenderer.js"></script>
     * 
     * Properties described here are passed into the $.jqplot function
     * as options on the series renderer.  For example:
     * 
     * > plot2 = $.jqplot('chart2', [s1, s2], {
     * >     seriesDefaults: {
     * >         renderer:$.jqplot.DonutRenderer,
     * >         rendererOptions:{
     * >              sliceMargin: 2,
     * >              innerDiameter: 110,
     * >              startAngle: -90
     * >          }
     * >      }
     * > });
     * 
     * A donut plot will trigger events on the plot target
     * according to user interaction.  All events return the event object,
     * the series index, the point (slice) index, and the point data for 
     * the appropriate slice.
     * 
     * 'jqplotDataMouseOver' - triggered when user mouseing over a slice.
     * 'jqplotDataHighlight' - triggered the first time user mouses over a slice,
     * if highlighting is enabled.
     * 'jqplotDataUnhighlight' - triggered when a user moves the mouse out of
     * a highlighted slice.
     * 'jqplotDataClick' - triggered when the user clicks on a slice.
     * 'jqplotDataRightClick' - tiggered when the user right clicks on a slice if
     * the "captureRightClick" option is set to true on the plot.
