I have a stage with no x,y specified. I expect it to be shown at the center of the screen but on prism, it does not appear at the center.

To reproduce the bug, run this code -

import javafx.scene.*;
import javafx.stage.*;
import javafx.scene.paint.*;
import javafx.scene.shape.*;
import javafx.scene.control.*;




Stage {
    width: 200
    height: 200
    scene: Scene {
     content: Rectangle {
     x: 40
     y: 40
     width: 100
     height: 100
     fill: Color.BLUE
}
}
}
---------

I reproduced it on WinVista - jdk6u14 - Soma-graphics-scrum-b142. Not reproducible on swing pipeline.
