title: WindowBuilder adds a LOT of unneeded empty Label
body: <p>I'm using Google's WindowBuilder to create UIs in Eclipse for desktop Java/SWT applications.
  I'm using Mac OS X.</p>
  
  <p>I've got this simple class (imports removed for clarity):</p>
  
  <pre><code>public class CustomersTab extends Composite {
      CustomersList mCustomersList;
      CustomerBadge mCustomerBadge;
      private final Table mtable;
  
      public CustomersTab(final Composite parent, final int style) {
          super(parent, style);
          setLayout(new GridLayout(3, false));
  
          final Composite leftPanel = new Composite(this, SWT.NONE);
          leftPanel.setLayoutData(new GridData(SWT.FILL, SWT.FILL, true, true, 1, 1));
          leftPanel.setLayout(new GridLayout(1, false));
  
          final Label lblRerchercher = new Label(leftPanel, SWT.NONE);
          lblRerchercher.setFont(SWTResourceManager.getFont("Lucida Grande", 13, SWT.BOLD | SWT.ITALIC));
          lblRerchercher.setText("Clients");
          mCustomersList = new CustomersList(leftPanel, SWT.NONE);
          mCustomersList.setLayoutData(new GridData(SWT.LEFT, SWT.TOP, true, true, 1, 1));
  
          final Label label = new Label(this, SWT.SEPARATOR | SWT.VERTICAL);
          label.setLayoutData(new GridData(SWT.LEFT, SWT.FILL, false, true, 1, 1));
  
          final Composite rightPanel = new Composite(this, SWT.NONE);
          rightPanel.setLayoutData(new GridData(SWT.FILL, SWT.FILL, false, false, 1, 1));
          rightPanel.setLayout(new GridLayout(1, false));
  
          mCustomerBadge = new CustomerBadge(rightPanel, SWT.NONE);
          mCustomerBadge.setLayoutData(new GridData(SWT.FILL, SWT.CENTER, false, false, 1, 1));
  
          final Label label_2 = new Label(rightPanel, SWT.NONE);
          label_2.setText("Détails");
          label_2.setFont(SWTResourceManager.getFont("Lucida Grande", 13, SWT.BOLD | SWT.ITALIC));
  
          mtable = new Table(rightPanel, SWT.BORDER | SWT.FULL_SELECTION);
          mtable.setLayoutData(new GridData(SWT.FILL, SWT.FILL, true, true, 1, 1));
          mtable.setHeaderVisible(true);
          mtable.setLinesVisible(true);
  
          final Label label_1 = new Label(this, SWT.SEPARATOR | SWT.HORIZONTAL);
          label_1.setLayoutData(new GridData(SWT.FILL, SWT.CENTER, true, false, 1, 1));
          new Label(this, SWT.NONE);
  
          final Label label_3 = new Label(this, SWT.SEPARATOR | SWT.HORIZONTAL);
          label_3.setLayoutData(new GridData(SWT.FILL, SWT.CENTER, false, false, 1, 1));
  
          final Button btnNewButton = new Button(this, SWT.NONE);
          btnNewButton.setImage(SWTResourceManager.getImage(CustomersTab.class, "/img/user_add.png"));
          btnNewButton.setLayoutData(new GridData(SWT.CENTER, SWT.CENTER, false, false, 1, 1));
          btnNewButton.setText("Nouveau client");
          new Label(this, SWT.NONE);
  
          Composite composite = new Composite(this, SWT.NONE);
          composite.setLayout(new GridLayout(1, false));
  
          Button btnModifierCeClient = new Button(composite, SWT.NONE);
          btnModifierCeClient.setImage(SWTResourceManager.getImage(CustomersTab.class, "/img/user_edit.png"));
          btnModifierCeClient.setText("Modifier ce client");
      }
  }

  <p>When I'm building my UI with WindowBuilder, it happens sometimes that it adds a lot of unused <code>Label</code>s like this:</p>
  
  <pre><code>public class CustomersTab extends Composite {

      private final Table mtable;

          setLayout(new GridLayout(3, false));
  
          final Composite leftPanel = new Composite(this, SWT.NONE);
          leftPanel.setLayoutData(new GridData(SWT.FILL, SWT.FILL, true, true, 1, 1));
          leftPanel.setLayout(new GridLayout(1, false));
  
          final Label lblRerchercher = new Label(leftPanel, SWT.NONE);
          lblRerchercher.setFont(SWTResourceManager.getFont("Lucida Grande", 13, SWT.BOLD | SWT.ITALIC));
          lblRerchercher.setText("Clients");
          mCustomersList = new CustomersList(leftPanel, SWT.NONE);

  <p>I have no idea why, and I'd like to know how to fix this because I have to switch back to the code view and remove the labels quite a lot, which makes me waste time.</p>
