/**
 * Performs configuration of the tree's renderer if the adapter's column is
 * the hierarchical column, does nothing otherwise.
 * <p>
 * 
 * Note: this is legacy glue if the treeCellRenderer is of type
 * DefaultTreeCellRenderer. In that case the renderer's
 * background/foreground/Non/Selection colors are set to the tree's
 * background/foreground depending on the adapter's selection state. Does
 * nothing if the treeCellRenderer is backed by a ComponentProvider.
 * 
 * @param component the rendering component
 * @param adapter component data adapter
 * @throws NullPointerException if the specified component or adapter is
 *         null
