+A physically-based material using the Cook-Torrance BRDF.
+
+The material is characterized by base color, metalness and roughness.  Fully
+metallic materials have no diffuse reflection and their specular reflection is
+tinted by the base color.  For fully dielectric materials base color determines
+the color of the diffuse reflection; specular reflection is untinted.
+Roughness affects how blurry specular reflections are.
