+ Prefer multitouch over single-touch axis ranges
+
+ We still use single-touch data in most cases, but sometimes the
+ multitouch axes have higher resolution. Since we use the same XI
+ valuators to report ST and MT data, we must pick one axis and scale the
+ other to match. This change picks the MT axis ranges.
