Re: [w3c/pointerlock] `movementX` and `movementY` for `pointermove` (and `pointerrawupdate`) should be the difference from the previous event for the same `pointerId` (Issue #104)

Thanks for filing this issue!

Before we look into this, I would suggest a simplified view of the problem here because PointerLock affects only _mouse_ pointers by definition, and that in practice no system exposes a non-primary mouse pointer (see the last "note" in [Section 4.1.2](https://w3c.github.io/pointerevents/#the-primary-pointer)). So I would suggest dropping the `pointerId` condition here and adding a line in the spec to emphasize that PointerLock is only about _primary_ mouse pointers. What do you think?
