The protocol requires that the emulated event is marked as such. So if a
driver with smooth scrolling axis sends legacy button events, the motion
event must be marked as emulated.
Pass the real type to emulate_scroll_button_events and create the events
accordingly. For real button press or relase events, only that event must be
generated since a release event will follow or a press event has already
occured, respectively. (This fixes a bug where we'd get two release events
for each legacy button event)
