Yeah, these break the concept of feedback versus control a bit.
Pointer acceleration has both categories. Maybe because these are
dynamically interacting with the user they are seen as special cases
that are a bit intermediate. I think it would have been better for
these both to have been kept as just controls and not feedbacks.
