-Added experimental source-skipping method to rpict for scenes

-rcontrib and separate srcsamp image-processing tool.  Controlling

+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.
+
+Added rad -N option to rholo call for multiprocessing when
+mkillum and/or mkpmap are involved in octree prep.
+
+Added ability of gendaymtx to read EPW as well as WEA files.
+When EPW input is provided, the 3-hour average dew point is
+used to compute a more accurate precipitable water content
+value.  It currently does not use these data directly from
+the EPW input, relying instead on a dew-point-to-W calculation.
+This follows the request and recommendations of David G-M.
+
+Removed limitation in rfluxmtx, which was disallowing distant
+and local receivers. Found this to be a perfectly valid approach
+for some annual daylighting scenarios.
+
+Wrote new pvsum tool to handle cases dctimestep can't, like
+spectral input pictures.  It also adds a -N option for multi-
+processing on Unix machines, which utilizes memory-mapped
+inputs for efficient i/o sharing.
+
+Made it so genBSDF can use spectral rendering for a
+more accurate photometric result.
