For scroll wheel support, we used to send buttons 4/5 and 6/7 for horizontal/vertical positive/negative scroll events. For touchpads, we really want more fine-grained scroll values. GetPointerEvents now accepts both old-school scroll button presses, and new-style scroll axis events, while emitting both types of events to support both old and new clients. This works with the new XIScrollClass to mark axes as scrolling axes. Drivers mark any valuators that send scroll events with SetScrollValuator. (Currently missing: the XIDeviceChangeEvent being sent when a driver changes a scroll axis at run-time. This can be added later.) Note: the SCROLL_TYPE enums are intentionally different values to the XI2 proto values to avoid copy/overlapping range bugs.
