Hi all,
there is still an issue with horizontal mouse wheels with latest VM, and
(Smalltalk sendMouseWheelEvents: true)

When I sweep the trackpad from bottom to top (with two fingers on MacBook),
I get  negative yDelta on the 3 OS, OSX, linux, Windows, all good.

When I sweep the trackpad from right to left (with two finders on Mac) , I
- negative xDelta on OSX
- positive xDelta on linux and Windows

I don't know whether it's due to Parallels VM, or same on native
windows/linux... Could someone confirm?

If so, I don't know which sign to change, what would you expect?
