--- Comment #9 from Peter Hutterer <peter.hutterer at who-t.net> ---
the direction locking is very mild, it's supposed to help with vertical
scrolling to not introduce any undue horizontal movement. There's a built-in
trigger that needs to be exceeded before we start sending events for the other
direction. It's definitely not a hard lock - you can scroll in all directions
at all times.

But your output above shows that it's (probably) working, you don't get any
horiz movement in the vertical scroll even though, most likely, you have the
odd horizontal event in the output.

yeah, that sounds good. I'm always in favour of localised variables that make
the code more obvious, the compiler optimises them away anyway.
