//! Class for the Muttenzer Box path tracing scene with soft gloss materials
/*! The same box and the same two spheres as AppDemoScenePTMuttenzerBox, with
one difference: the shininess of the mirror sphere and both the translucency
and the shininess of the glass sphere are 100 instead of SLMaterial::PERFECT
(1000). Below that limit the path tracer draws the direction from the Phong
lobe of the exponent (SLRay::reflectMC and SLRay::refractMC) instead of taking
the perfect specular one, so the mirror sphere reflects blurred and the glass
sphere is frosted in its refraction as well as in its surface reflection. The
glass sphere is also given a red transmissive color, which makes its caustic on
the floor red. Only the path tracer shows any of this; the OpenGL preview and
the ray tracer render the scene exactly like the original.*/
