XIScrollClassInfo, generation of "smooth" scroll events from replayed buttons

[Thomas Lübking]

See https://bugzilla.gnome.org/show_bug.cgi?id=750870

KWin passively grabs and casually replays buttons (including 4,5,6 & 7) on inactive windows, but apparently that does not lead to the generation of "smooth" scroll events from xinput2.

I suspect this could be related to the replay also generating framing enter/leave events (at least I hope that's not somehow us causing them ;-)

=> Is this somehow still supposed to work?

Cheers,
Thomas
