Element by element...when calculating diffuse, the diffuse values would 
be interpolated, etc.

All the other maps (except slope_map, which is rather unusual) are 
linearly interpolated. I think it would lead to the best and most 
predictable results, though I've often wondered if quadratic and cubic 
options would be useful for color maps.

Again, I think the best solution would be to have each attribute 
individually mappable, but that is not practical in the current POV-Ray.
