[Haskell-cafe] How do you change the mouse position?

In C++, maybe Java, I remember using a Robot to change the location of the mouse on the screen. My intention is to do something like in an FPS game where the mouse is always centered to make sure it doesn't run into the edges of the screen. How can I do that in Haskell? I'm using OpenGL, so if there is a utility that specifically works with OpenGL then I believe that would be the most helpful. -Eitan
