I am trying to implement resize from all sides of a window, this requires both resizing and moving the window. In JavaFX 1.3 we implemented in such a way that the setX,Y,Width,Height methods on Stage did nothing but store the new value and mark dirty. Then on the next pulse the window was moved and resized in one call. This was important to avoid jittering when resizing the window.

I have attached my Windows Resize helper class, just create a instance and pass in root Region and stage and it will add drag resize support to the stage.
