The correct way to move the pointer is indeed to write a IECLASS_POINTERPOS
event to the input.device.

However, remember that the pointer is an extension of the user's hand.
Constraining the pointer is hardly better than tying his hand.  Even
without knowing your application, I'd bet there's a 90% chance that
you'd be better off letting the pointer move freely.  Pointer constraints
are normally unnatural and confuse users.
