+Subject: Force x/y axes to exist on devices with any other axes (#44655)
+
+Too much in the server relies on x/y to exist and to be axes 0 and 1. So if
+any relative axes exist, initialize REL_X/Y or ABS_X/Y as well.
+
+For servers up to 1.11: a scrollwheel-only device now has relative axes
+where it only had buttons before.
+
+For servers 1.12 or later: the device now has x/y in addition to the scroll
+axes.
