The keyword diffuse is used in a finish statement to control how much of the light coming directly
from any light sources is reflected via diffuse reflection.
For example
finish { diffuse 0.7 }
means that 70% of the light seen comes from direct illumination from light sources.
The default value is diffuse 0.6.
