Thanks.  Just for my education, what happens when you translate a slope map? My
experience is "nothing", and understanding why would help me understand the
inner workings of the function.  I was hoping it would be like "the slope of the
model at a [vector V] away", but it wasn't.   thanks.  As I'm typing, I think I
should re-read section on warps!
