Comment 10 for bug 605353

I've just removed the change between 17.2 and 1.8.0. Now the wheel control has no adjustment whatsoever -- its value is added directly to the rate.

There are two MIDI devices in the repo that use the wheel control so the scope of this change is almost purely waveform-related, though it helps to not change behavior with respect to 1.7.0 if possible. Everyone who wants a more sensitive wheel can just use script to adjust the sensitivity.
