wheel emulation, for some reasons beyond time, got the value from pEvdev->vals, then set the value back into pEvdev->vals. Alas, that value is always 0, hence oldValue is zero and the delta is nil. If we're not in relative (touchpad) mode, store the current value in old_vals, so they're retrievable for the next event.
