// * A menu for window creation in the workbench.  
// * <p>
// * An <code>OpenPerspectiveMenu</code> is used to populate a menu with
// * actions that will open a new perspective. If the user selects one of 
// * these items either a new page is added to the workbench, a new 
// * workbench window is created with the chosen perspective or the current
// * perspective will be replaced with the new onw.
// * </p><p>
// * The visible perspectives within the menu may also be updated dynamically to
// * reflect user preference.
// * </p><p>
// * The input for the page is determined by the value of <code>pageInput</code>.
// * The input should be passed into the constructor of this class or set using
// * the <code>setPageInput</code> method.
// * </p><p>
// * This class may be instantiated; it is not intended to be subclassed.
// * </p>
// * @deprecated  See IWorkbench.showPerspective methods.
