To be honest, I haven't seen a significant difference in render times
between method 1 and method 2. ISTR that method 1 allowed the user to
optionally specify a max_gradient, and that it was often necessary to do
so for complicated isosurfaces to render without artifacts anyway, so
I'd say you've lost nothing. I admit to not testing this, however...
