title: How to get filtered rows from GridX?
body: <p>I'm using Dojo GridX with many modules, including filter:</p>
  
  <pre class="lang-javascript prettyprint-override"><code>grid = new Grid({
      cacheClass : Cache,
      structure: structure,
      store: store,
      modules : [ Sort, ColumnResizer, Pagination, PaginationBar, CellWidget, GridEdit,
           Filter, FilterBar, QuickFilter, HiddenColumns, HScroller ],
      autoHeight : true, autoWidth: false,
      paginationBarSizes: [25, 50, 100],
      paginationBarPosition: 'top,bottom',
  }, gridNode);
  grid.filterBar.applyFilter({type: 'all', conditions: [
      {colId: 'type', condition: 'equal', type: 'Text', value: 'car'}
  ]})
  </code></pre>
  
  <p>I've wanted to access the items, that are matching the filter that was set. I've travelled through <code>grid</code> property in DOM explorer, I've found many store references in many modules, but all of them contained all items.</p>
  
  <p>Is it possible to find out what items are visible in grid because they are matching filter, or at least those that are visible on current page? If so, how to do that?</p>
