Since this version, I've added a check for the abi version for masked
valuators. I assume 1.10 will end up at major abi version 13 if I read
Peter's replies correctly, so I set a requirement for it.

I haven't added a check for multitouch abi simply because the abi
version it will go in at hasn't been determined yet.
