WDYT about the following passage?

  @cindex pixel-resolution wheel events
  You can use @var{x} and @var{y} to determine how much the mouse wheel
  has actually moved.  Scrolling the screen by these pixel deltas allows
  to present movement that appears to follow the user's grip on the
  mouse wheel.

Thanks.
