Centering Nodes/Text - Vertically & Horizontally

Question

Since JavaFX v1 was released overnight the ability to align text VERTICALLY and horizontally has been removed/changed.
Horizontal alignment is more or less the same as there is Text.textAlignment
Vertical alignment is now missing. In preview1 we could set and x/y for the Text and then we could also set vertical alignment on the Text: [SEE HERE|http://javafx.com/releases/preview1/docs/api/javafx.scene/javafx.scene.VerticalAlignment.html]. Just bind a translation to the middle x/y of the parent.
Using v1 I would expect the to see "BLAH" in the middle of the scene:
public class CenteredText extends Text {
        override var textAlignment = TextAlignment.CENTER;
        override var textOrigin = TextOrigin.TOP;  //???
        override var translateX = bind (boundsInParent.width - boundsInLocal.width) / 2 ;
        override var translateY = bind (boundsInParent.height - boundsInLocal.height) / 2 ;
function run(){
    Stage {
        title: "BLAH"
        scene: Scene {
            width: 800
            height: 400
            content: [
                CenteredText{
                    content: "BLAH"}
}}Finally, this is not really a requirement of Text, all nodes should be able to align themselves in the middle of their parent.

Hello dgrieve,
You suggest using "parent" instead of "scene" for the general case, however, I cannot get this to work. I put the text in a Group as you mentioned, but I just get a StackOverflowError. This is using parent.boundsInLocal as well as parent.boundsInParent.
Could you or anybody look at the following code to see what I did wrong? Thank you.
import javafx.scene.text.Text;
import javafx.scene.text.TextAlignment;
import javafx.scene.text.TextOrigin;
import javafx.scene.Scene;
import javafx.stage.Stage;
import javafx.scene.Group;
public class CenteredText extends Text {
   override var textAlignment = TextAlignment.CENTER;
   override var textOrigin = TextOrigin.TOP;
//   override var translateX = bind (scene.width - boundsInLocal.width) / 2 ;
//   override var translateY = bind (scene.height - boundsInLocal.height) / 2 ;
   override var translateX = bind (parent.boundsInLocal.width - boundsInLocal.width) / 2 ;
   override var translateY = bind (parent.boundsInLocal.width - boundsInLocal.height) / 2 ;
//   override var translateX = bind (parent.boundsInParent.width - boundsInLocal.width) / 2 ;
//   override var translateY = bind (parent.boundsInParent.width - boundsInLocal.height) / 2 ;
    public function run(args : String []) : Object {
        Stage {
            title: "Vertical and Centered Text Node Example"
            scene: Scene {
                width: 800
                height: 400
                content: [
                    Group {
                        content: [
                            CenteredText{
                                content: "ONE\nTWO\nTHREE\nFOUR"
}
