REVISION SUMMARY
  So far KWin didn't send axis_source, axis_discrete, and axis_stop. Even
  though most of those events are optional, clients need them to work as
  expected. For example, one needs axis_source and axis_stop to implement
  kinetic scrolling; Xwayland needs axis_discrete to prevent multiple
  scroll events when the compositor sends axis deltas greater than 10, etc.
