/****
 *
 * BoxPanel is an implementation of JFC's Box as a JComponent, so alignment
 * operations can be performed on it.  The only real work is in the
 * re-implementations of createHorizontalBox and createVerticalBox, which
 * return new instances of this JComponent-extending class instead of the
 * Component-extending Box.
 *
 * This BoxPanel class is obsoleted by the 1.4 upgrade of Box, so BoxPanel is
 * only needed in 1.3 code and earlier.
