/**
 * The <code>JsFrameBorder</code> class is for the integration of the operations
 * on the eight border blocks indicated by the following constraints in the <code>JsFrame</code>:
 * <p>
 * <ul>
 * <li><code>NORTHWEST</code>(defined in <code>JsFrameBorderBlock</code>):
 * The northwest portion of the layout for the <code>JsFrame</code>.
 * <li><code>NORTH</code>(defined in <code>JsFrameBorderBlock</code>):
 * the north portion of the layout for the <code>JsFrame</code>.
 * <li><code>NORTHEAST</code>(defined in <code>JsFrameBorderBlock</code>):
 * The northeast portion of the layout for the <code>JsFrame</code>.
 * <li><code>WEST</code>(defined in <code>JsFrameBorderBlock</code>):
 * The west portion of the layout for the <code>JsFrame</code>.
 * <li><code>EAST</code>(defined in <code>JsFrameBorderBlock</code>):
 * The east portion of the layout for the <code>JsFrame</code>.
 * <li><code>SOUTHWEST</code>(defined in <code>JsFrameBorderBlock</code>):
 * The southwest portion of the layout for the <code>JsFrame</code>.
 * <li><code>SOUTH</code>(defined in <code>JsFrameBorderBlock</code>):
 * The south portion of the layout for the <code>JsFrame</code>.
 * <li><code>SOUTHEAST</code>(defined in <code>JsFrameBorderBlock</code>):
 * The southeast portion of the layout for the <code>JsFrame</code>.
 * </ul>
 * <p>
 * If you just want to operate some of the above border blocks, you should first get it 
 * from the layout of the <code>JsFrame</code> by doing the following:
 * <pre>
 * JsFrameLayout layout = (JsFrameLayout) jsframe.getLayout();
 * Component component = layout.getLayoutComponent(JsFrameLayout.NORTHWEST);
 * </pre>
 * or doing the following:
 * <pre>
 * JsFrameLayout layout = (JsFrameLayout) jsframe.getLayout();
 * JsComponent jscomponent = (JsComponent) layout.getLayoutComponent(JsFrameLayout.NORTHWEST);
 * </pre>
