     * @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
