  27  * Provides one interface and many abstract classes that Swing uses to provide
  28  * its pluggable look-and-feel capabilities. Its classes are subclassed and
  29  * implemented by look and feel UIs such as Basic and the Java look and feel
  30  * (Metal). This package is only used by developers who cannot create a new
  31  * look and feel by subclassing existing look-and-feel components (such as those
  32  * provided by the {@code javax.swing.plaf.basic} and
  33  * {@code javax.swing.plaf.metal} packages).
  34  * <p>
  35  * <strong>Note:</strong>
  36  * Most of the Swing API is <em>not</em> thread safe. For details, see
