[Bf-funboard] Volumetric normals based on density gradient?

How big would the impact in the performance be if the normals for
volumetric materials were calculated based on the density gradient (i guess
sampling N points around the point in question to see which direction is
denser; averaging the directions in case there was disagreement)?

And for homogenous density regions perhaps it could do something like
produce a <0,0,0> normal internally that gets treated as a sorta wildcard,
pointing back at the direction of incoming rays?
