I guess I should clarify my last point, i'm aware that changing the
vertical scaling will have a direct effect on the slope. What I'm trying
to do is create a smoothly contoured gradiant over large odd shaped areas
in the heightfield image. It would be nice to do this in a somewhat direct
way, rather than by going through a multiple trial and error filtering
process.
