       * 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.
