There are two scroll modes: the default 2d scroll mode is essentially
only useful for touchpads, because mice cannot scroll horizontally, so
scrolling up/down to get to the next workspace will get users confused.
By setting the scroll_mode to 1 users get a simple way of scrolling
through workspaces, irrespective of the number of rows the pager sets.
