pub trait MouseRelativeEvent: Sized {
    fn from_pos(x: [f64; 2], old_event: &Self) -> Option<Self>;

    fn mouse_relative<U, F>(&self, f: F) -> Option<U>
    where
        F: FnMut([f64; 2]) -> U;

    fn mouse_relative_args(&self) -> Option<[f64; 2]> { ... }
}

The relative movement of mouse cursor.
