      * @param	value		the value of the cell to be rendered.  It is
      * 				up to the specific renderer to interpret
      * 				and draw the value.  For example, if
      * 				<code>value</code>
      * 				is the string "true", it could be rendered as a
      * 				string or it could be rendered as a check
      * 				box that is checked.  <code>null</code> is a
      * 				valid value
      * @param	isSelected	true if the cell is to be rendered with the
      * 				selection highlighted; otherwise false
      * @param	hasFocus	if true, render cell appropriately.  For
      * 				example, put a special border on the cell, if
      * 				the cell can be edited, render in the color used
      * 				to indicate editing
      * @param	row	        the row index of the cell being drawn.  When
      * 				drawing the header, the value of
      * 				<code>row</code> is -1
      * @param	column	        the column index of the cell being drawn
