 Added strnstr.c compatibility module in ray/src/common, since
 it isn't present on Linux-derivatives.
+
+Added WGMDfunc material type with programmable roughness and
+separate modifier paths for the different components.
+
+Added gensurf -i option at the request of Peter Apian-Bennewitz
+to reverse surface normals, mostly for data input when it is
+a bit more difficult to adjust.

+Simplified synchronization between processes sharing indirect
+irradiance values via an ambient file. Removed file locking
+operations in favor of simpler operation relying on O_APPEND flag.
+Not sure if this will have any affect on shared filesystems, but
+it should reduce overhead for massively parallel machines.
+
+Added rad -N option to rholo run for multiprocessing when
+mkillum and/or mkpmap are involved in octree prep.
