There should be an additional mention of not using the averaged normals 
approach, but using a single normal plus focal blur and antialiasing.

Clipka talks about this approach here:

The code I used is this:

		pigment { InPigment }
		finish { InFinish }
		normal { InNormal }
		normal {bumps BlurAmount scale 0.01}

along with some focal blur and antialiasing.

I'm not sure how the section should be worded however.
