Yep, and if you need it to point from the x plane, getting thinner along the
x axis toward +x you would add: up x or up <1,0,0> (this would mean -1*x
not -1*y for the offset if so done).  Fog thickness is at 25% when it
reaches fog_offset+fog_alt and the background is 36.8% visible at 'distance'
you give it also (if no transparency is specified).
