A relative wheel is not currently supported on the tablet pad interface, causing errors in this form:
libinput error: event10 - Wacom Graphire4 6x8 Pad: Unexpected event type EV_REL (0x2)
This requires full support for wheel events in the libinput tablet pad interface.
libwacom PR: https://github.com/linuxwacom/libwacom/pull/23, at the time of this issue libwacom was missing support.
