With the finish statements that specify a brightness (reflection,
ambient, diffuse, phong, specular), it should be similar. With
statements that specify a size or falloff (brilliance, roughness,
phong_size), it would be like "gamma correcting" the radius of a sphere,
which is of course nonsense.
And don't forget your lights.
