Bug 267425 [Perspectives] problem with outline view and min/max
bundles/org.eclipse.ui.views/src/org/eclipse/ui/views/properties/PropertySheet.java
* same thing as property <it>dialogs</it> and their property pages (the property
 * pages extension point is for contributing property pages to property dialogs).
 * Within the property sheet view, all pages are <code>IPropertySheetPage</code>s.
 * </p>
 * <p>
 * Property sheet pages are discovered by the property sheet view automatically
 * when a part is first activated. The property sheet view asks the active part
 * for its property sheet page; this is done by invoking 
 * <code>getAdapter(IPropertySheetPage.class)</code> on the part. If the part 
 * returns a page, the property sheet view then creates the controls for that
 * property sheet page (using <code>createControl</code>), and adds the page to 
 * the property sheet view. Whenever this part becomes active, its corresponding
 * property sheet page is shown in the property sheet view (which may or may not
 * be visible at the time). A part's property sheet page is discarded when the
 * part closes. The property sheet view has a default page (an instance of 
 * <code>PropertySheetPage</code>) which services all parts without a property
 * sheet page of their own.
 * </p>
 * <p>
 * The workbench will automatically instantiates this class when a Property
 * Sheet view is needed for a workbench window. This class is not intended
 * to be instantiated or subclassed by clients.
