I meant to say that those angle deltas only make sense as part of a
pinch event, and they're not supposed to be treated as separate rotation
events.  (Which we will want to expose to Lisp separately, once the
XInput developers add support for them.)

Yes, but it solves the flickering problem.

Yes, but limiting the frequency of these events is something not all
commands might want.

Thanks.
