Touchpad scrolling should only scroll on one axis at a time
Submitted by Ralf
On my document viewers, when I use two-finder-scrolling with my touchpad, the document is only ever scrolled either vertically or horizontally. This is very useful. I frequently work with PDF documents that have significant margin (useful for the printed version). I set my the zoom such that the text fills the evince window horizontally, so the margins are "cut off". In this situation, it is virtually impossible to reasonably use the touchpad to scroll -- the document will inadvertently move a little bit to the left or to the right, moving some text out of the view.
Evince should behave like other document viewers and stick to one axis when doing touchpad-scrolling.
