# A "material Phenomenon" can include other types of shaders just like
# a material.  In this case, the "glambert" material Phenomenon
# includes a photon shader using the same diffuse color that the
# "lambert" shader does.  Notice that the "ambient" component is
# supplied to "lambert" by shader "average_radiance" using the typical
# "=" syntax for shader referencing.
