/**
 *  Used to initialize the DataGrid's <code>rowBackground</code> skin part.   
 *  If the <code>alternatingRowColors</code> style is specified, 
 *  then use the <code>alternatingRowColorsBackground</code> skin part 
 *  as the value of the <code>rowBackground</code> skin part.  
 *  The alternating colors for the grid rows are defined by 
 *  successive entries in the Array value of this style.
 *
 *  <p>If you want to change how this style is rendered, 
 *  replace the <code>alternatingRowColorsBackground</code> skin part
 *  in the DataGridSkin class.   
 *  If you want to specify the background for each row, then 
 *  initialize the <code>rowBackground</code> skin part directly.</p>
