John Beard ce758adca3 Enable horizontal scroll panning
Allow a horizontal scroll event to fall through to the panning branch.

This still restricts zooming to use only the vertical axis, but it
(re-?)enables the horizontal pan function that currently doesn't work
even if the user has set "allow horizontal panning", as the horizontal
scroll doesn't have a modifier, which is the default for vertical scroll
zoom, and thus it skips over the whole panning branch.

If the user has not set horizontal panning, the earlier early return
means that there is no handling of any horizontal scroll event, so this
won't change anything for these users.
