  *  positions and sizes rather than constraints to define the layout.
  *  DataGrid's with <code>variableRowHeight="false"</code> (the
  *  default) tend to perform better, likewise for
- *  <code>showDataTips="false"</code> (also the default).</p>

  *  <p>Examples of the various GridItemRenderer configurations described 
  *  here are available in the examples section.</p>

 *  <p>Item renderers are associated with each column of a grid.
 *  Set the item renderer for a column by using 
 *  the <code>GridColumn.itemRenderer property</code>.</p> 
 * 
 *  <p>Transitions in DataGrid item renderers aren't supported. The GridItemRenderer class 
 *  has disabled its <code>transitions</code> property so setting it will have no effect.</p>

 *  as text is to identify the GridItemRenderer's text displaying
 *  element with <code>id="labelDisplay"</code>.  The labelDisplay
 *  component must be a <code>TextBase</code> subclass like
 *  <code>Label</code> or <code>RichText</code>.  You might take this
 *  approach, instead of just using DefaultGridItemRenderer, if your
 *  item renderer included some additional elements that did not
 *  depend on the item renderer's data, like borders or other graphic
