I also need the getX() and getY() method in Display so that I can replace the current functionality provided by setParent() in my TWL Theme Editor.
This app remembers it's last size and position so that it can reopen in the same location next time. Currently the native resizing can't be used because it has no way to query the current position.
I propose the following methods to be added to Display:
getX() or getLocationX()
getY() or getLocationY()
wasMoved() analog to wasResizied()
