[Bug 1228250]

[Thomas Mitterfellner]

I have never owned a mouse with a horizontal scroll wheel, only ones
with a tiltable a scroll wheel. It's horrible having to use those for
scrolling horizontally as you have to press them several times rather
than rotate a wheel. It feels much more natural to use the up/down wheel
with a modifier key pressed.

Furthermore, this is standard behavior in quite a number of
applications; to the ones already mentioned (Chrome, gimp, evince) I'd
like to add Inkscape, Scribus, LibreOffice. For other applications like
konqueror, okular, gwenview, qtcreator it's Alt+Scroll Wheel, but still
it's possible.

I frequently find myself longing for that feature because I (have to)
use large zoom levels and having to grab the scroll bar or scroll with
Left/Right keys is much less comfortable. So I would be really happy if
someone could provide a simple working solution! (o:
