 Altered BSDF library to have both front and back diffuse transmittance
 values, which can be different.  This was necessary to avoid issues
 caused by measurement and modeling discrepancies.

+Added pabopto2bsdf -g option to cull near-grazing scattering to avoid
+issues with noise and negative values.
+
+Increased default dynamic range from 32 to 100 in pcond and normtiff.

+Added -o and -n options to genbox to create .OBJ output and segment
+edges and corners for transparent materials.  Also added -s option
+to control smoothing for .OBJ and Radiance with segmented rounding.
+
+Made it so robjutil with the +r option for Radiance output now
+produces normal smoothing unless normals are removed with -n.
