title: How to stop the mouse from exiting the window?
body: <p>I have a javafx game which by the way is running as a windowed app. The game is controlled by moving and clicking the mouse but my problem occurs when I move the mouse too far and it goes outside the window, since as I mentioned clicking is also part of the game, and we all know what happens when you click the program that is behind your windowed app, say if I click google chrome by accident, and my game is then hidden behind google chrome, but since it's still running I lose unless I am able to alt+tab quick enough back into the game.</p>
  <p>I wish to solve this problem by not allowing the mouse to exit the window, constraining it to the boundaries of the window/stage/scene that my game is running in.</p>
  <p>Is it possible to constrict the mouse like this? How should I do so?</p>
