Hello Jason
I tried your recommendation *how you figured this out I will never understand* it worked on GTK3 examples and reversed the scroll direction for evince.... but now any other non GTK3 program the reverse scrolling direction feature *as set in the mouse settings panel in xfce* is not obeyed.
