If it was a blur effect, it would work with the facets pattern (it would 
also be slower). It is just a reduction in accuracy. Small features 
aren't blurred out, the gradient of the pattern just isn't sampled as 
finely, so small details aren't picked up. The facets pattern doesn't 
have a gradient, it is solved in a different way, so it won't work with 
this trick. A true blur would work though.

Make an average texture of several textures with randomly jittered 
normals...that's a blur. The effect of reducing the accuracy is just to 
make the sample points farther apart, not to spread out the existing 
features which is what a blur is.
