title: Jvectormap markers draw wrong after setFocus call
body: <p>I want to focus on US state on selection of an US state. The code is this:</p>
  
  <pre><code>    var ddd = {
          "US-VA": 1,
          "US-PA": 1,
          "US-TX": 1,
          "US-RI": 1,
          "US-SC": 1,
          "US-OR": 1,
          "US-CO": 1,
          "US-KY": 1
      };
      var map = {};
  
    $(function(){
      map = new jvm.WorldMap({
          map: 'us_aea_en',
          backgroundColor: '#EEEEEE',
          container: $('#us-map'),
          regionsSelectable: true,
          regionsSelectableOne: true,
          regionStyle: {
              initial: {
                  fill: '#777777',
                  "fill-opacity": 1,
                  stroke: 'none',
                  "stroke-width": 0,
                  "stroke-opacity": 1
              }
          },
          series: {
              regions: [{
                  values: ddd,
                  scale: ['#FF6633', '#FF6622'],
                  normalizeFunction: 'linear'
              }]
          },
          markerStyle: {
          initial: {
          fill: '#F8E23B',
          stroke: '#383f47'
          }
          },
          markers: [
              {latLng: [41.17, -74.92], name: 'New York'},
              {latLng: [34.06, -118.25], name: 'Los Angeles'},
              {latLng: [29.98, -95.54], name: 'Houston'},
              {latLng: [42.42, -71.3], name: 'Boston'},
              {latLng: [32.79, -96.81], name: 'Dallas'},
              {latLng: [32.79, -79.95], name: 'Charleston'},
              {latLng: [38.02, -122.89], name: 'San Francisco'},
              {latLng: [35.17, -106.86], name: 'Albuquerque'},
              {latLng: [35.72, -97.99], name: 'Oklahoma City'},
              {latLng: [61.22, -149.91], name: 'Anchorage'},
              {latLng: [21.47, -158.08], name: 'Honolulu'}
          ],
          //onRegionSelected: function(event, isSelected, selectedRegions){
          onRegionSelected: function(selectedRegions){
              map.setFocus(9, selectedRegions);
          }
        });
      });
  </code></pre>
  
  <p>When I select a region the markers are drawn in the wrong location. A small shift is seen, like the map try to <code>setFocus</code>, but the markers go in the left up corner.
  I use <strong>jvectormap-1.1.1.min.js</strong> and <strong>jquery-1.8.3.min.js</strong></p>
  
  <p>Here is the map when loaded:

  <p>Here is the map after selecting a state:

  <p>Any clue?</p>
