Comment 18 for bug 951123

Sebastien:
I've tested the if my macbook pro pad registers natural scrolling and it does not. To clarify, when my fingers glide over the pad towards me, the on-screen document scrolls to the bottom of the page rather than to the top (as it should in natural/reverse scrolling).

So unless setting 5 before 4 in .Xmodmap is screwing up a gtk's already implemented, it's still a problem on pads, nor is it working with mice.

As for gnome picking up this feature because it's part of gtk, well, I've looked at Unity's mouse preference pane and there's nothing called smooth scrolling there, much like the case with nautilus' preference pane, too.

As for that term, "smooth scrolling" is confusing and reading about it on the net shows that some talk about literally "smooth" transitions from top to bottom (& vice versa) in any document, as opposed to jerky movement (jumping 2 or 3 lines with each movement of the wheel of the mouse). Again, to be clear, I believe both Ronald and I are not referring to this feature. We're only concerned with, as is this bug, the cause and effect of directionality of movement with any and all pointer apparatus.
