Axis changes are now still processed by libinput regardless of whether or not the tool is in proximity, however we refrain from reporting them unless the tool is in proximity. This stops bad distance events from being reported without needing a huge mess of conditional statements in sanitize_axes(). The tool is now counted as back in proximity when a tool update is received instead of when an axis update is received.
