title: Graphael pie.js unhover event missing
body: <p>Graphael doesn't have an unhover event for some odd reason. Found this chunk of code in pie.js that creates hover events:</p>
  
  <pre><code>chart.hover = function (fin, fout) {
      fout = fout || function () {};
  
      var that = this;
  
      for (var i = 0; i &lt; len; i++) {
          (function (sector, cover, j) {
              var o = {
                  sector: sector,
                  cover: cover,
                  cx: cx,
                  cy: cy,
                  mx: sector.middle.x,
                  my: sector.middle.y,
                  mangle: sector.mangle,
                  r: r,
                  value: values[j],
                  total: total,
                  label: that.labels &amp;&amp; that.labels[j]
              };
              cover.mouseover(function () {
                  fin.call(o);
              }).mouseout(function () {
                  fout.call(o);
              });
          })(series[i], covers[i], i);
      }
      return this;
  };
  </code></pre>
  
  <p>The unhover event is Raphael JS is the following code snippet. Using these two there must be a way to create an unhover for a Grapael pie chart. Any help here will be very very greatly appreciated as I'm stumped!</p>
  
  <pre><code>elproto.unhover = function (f_in, f_out) {
      return this.unmouseover(f_in).unmouseout(f_out);
  };
  </code></pre>
