--- Comment #3 from Peter Hutterer <peter.hutterer at who-t.net> ---
Test packages for the three outlined above:
1) 3mm threshold: http://koji.fedoraproject.org/koji/taskinfo?taskID=10152166
2) last-delta: http://koji.fedoraproject.org/koji/taskinfo?taskID=10152173
3) replay: http://koji.fedoraproject.org/koji/taskinfo?taskID=10152180

Note that 3 is the technically best solution but is mostly pointless in X since
we don't use the event timestamps - the server adds their own. So I don't
expect that to be much of an improvement. This may actually work better in a
pure wayland context but even there I doubt it since the events still come in
simultaneously and thus render at the same time.


For 2: that's not the complete solution yet since it'll have the same deadzone
for scroll timeouts (and we def. don't want that). I just felt lazy :)
