Sending separate axis events instead of one unified events is limiting, especially when simultaneously scrolling in both directions and the caller tries to implement kinetic scrolling. Take a page from the tablet-support branch and instead implement the axis event as a generic event that can contain multiple axes simultaneously. Right now we only have two (scroll) axes and we could easily just check both for non-zero values. If we want to allow further axes in the future, we need a check whether an axis is set in an event, that's what libinput_event_pointer_has_axis to scroll events() is for. We also need the mask to notify of a scroll stop event, which could otherwise be confused as a vertical-only or horizontal-only event. This is an API and ABI break.
