 * Issue #258-swingx: Background LegacyHighlighter must not change custom

 * <p>
 * 
 * Visualizing effect of hack: table-internally, a ResetDTCRColorHighlighter
 * tries to neutralize DefaultTableCellRenderer's color memory.
 * 
 * <ul>
 * <li> a DTCR with custom foreground and custom background
 * <li> the renderer is shared between a table with background highlighter
 * (alternateRowHighlighter) and a table without highlighter
 * <li> the custom foreground must show in both
 * <li> the custom background must show in the table without highlighter
 * <li> the custom background must not show in the table with highlighter
 * (AlternateRowHighlighter overwrite both striped and unstriped back)
 * </ul>
