Bug 114999 Use larger font in text area of Expression Builder
I liked the larger font used in the expression area of the old Expression Builder. The larger font makes it easier to read an expression that contains multiple statements.

sourceViewer.doOperation( ITextOperationTarget.REDO );

	private void createExpressionField( Composite parent )
	{
		Composite expressionArea = new Composite( parent, SWT.NONE );
		expressionArea.setLayout( new GridLayout( 2, false ) );
		expressionArea.setLayoutData( new GridData( GridData.FILL_BOTH ) );
		Composite composite = new Composite( expressionArea, SWT.BORDER );
		composite.setLayoutData( new GridData( GridData.FILL_BOTH ) );
		composite.setLayout( UIUtil.createGridLayoutWithoutMargin( ) );
		CompositeRuler ruler = new CompositeRuler( );
		ruler.addDecorator( 0, new LineNumberRulerColumn( ) );
		sourceViewer = new SourceViewer( composite, ruler, SWT.H_SCROLL
				| SWT.V_SCROLL );
		sourceViewer.configure( new JSSourceViewerConfiguration( ) );
		
		
		if ( expression != null )
		{
			JSEditorInput editorInput = new JSEditorInput( expression );
			JSDocumentProvider documentProvider = new JSDocumentProvider( );
			try
			{
				documentProvider.connect( editorInput );
			}
			catch ( CoreException e )
			{
				ExceptionHandler.handle( e );
