Capture mouse in a bounding box?

I have a few use cases for this sort of thing, I use the Robot class to reposition the mouse cursor to solve it.  Is there an official Robot for JavaFX in 8.0?

Some other cases:

- A control that you grab and while the button is pressed the mouse is spinning a wheel or something like that.  You don't want the cursor to hit the edge of the screen and stop sending events.

- Aiming in a first-person shooter.. same thing, you want to keep getting events, so you must prevent the mouse cursor from hitting a screen edge.

Frankly, I don't think it will get a high priority unless you provide really compelling reason for it (I don't think it's an encouraged pattern, usually it's pretty frustrating for the user when the mouse doesn't move).
