- introduced SurfaceGeometry to carry all the geometric information input to
BRDF sampling and evaluation functions.
- made Reflectance keep an (optional) pointer to its material
- simplified PhongRefl::sample_dir, with the help of SurfaceGeometry
- worked around microsoft's broken std::thread implementation's deadlock on join
