/**
 * Disables the scrolling behaviour of the nearest scrollpanel found in the given widget's containment hierarchy.
 * <p>/*from w  w w  . ja  v a  2  s  .co m*/
 * FIXME this is a really horrible workaround! should instead modify UF API to allow PanelDefinition to opt out of having a scroll panel.
 * The better fix would require changes to:
 * <ul>
 * <li>WorkbenchPartPresenter.View
 * <li>WorkbenchPartView and its mock
 * <li>The @WorkbenchPanel annotation
 * <li>The annotation processor code generators and their tests
 * </ul>
 * @return true if a scroll panel was found and disabled; false if no scroll panel was found.
