+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.
-+
-+
+Added exposure preservation to pcompos when possible (i.e., when
-+
+there is only one input or inputs agree on exposure).
-+
-+
+Added -DSHARP_RGB compile-time option to use sharp RGB color space
-+
+rather than historic default.  This can make for more accurate color
-+
+calculations, but requires that materials be recalibrated.  The
-+
+PRIMARIES= line is also produced on output from rpict or rvu with
-+
+the correct set of primaries based on how the system was compiled.
-+
-+
+Added automatic flushing to the output of total, except when the -r
-+
+(running subtotals) option is used.
-+
-+
+Improved behavior of little-used -aw option, so that it avoids sea-level
-+
+rise caused by adding its own estimate back into the ambient level remainder.
-+
+It ended up being simple enough to derate the final average by the factor
-+
+corresponding to average surface absorpition, thus removing the average
-+
+from the final bounce estimate.
-+
-+
+Introduced ies2rad upgrades by Randolph Fritz.  Randolph says it
-+
+fixes the following problems:
-+
-+
+. Generates correct Radiance geometry for spheres in 1995, 2002,
-+
+        and 2019 IES files.
-+
-+
+. Generates correct Radiance geometry for vertical cylinders that
-+
+        are taller than they are wide.
-+
-+
+. Ignores the file source ("File Generation Type") field in the
-+
+version of the file, which would otherwise be incorrectly used
-+
+        as an output multiplier.
-+
-+
+    It also offers the following enhancements:
-+
-+
+. Shape information is included in the .rad file comments.
-+
-+
+. 1995, 2002, and 2019-version luminous opening geometry is
-+
+        accounted for.
-+
-+
+. The 2002 and 2019 IES file versions are recognized and
-+
+        processed appropriately.
-+
-+
+. I have made an attempt to do something intelligent with less
-+
+        common "luminous opening" shapes in the 1995, 2002, and 2019 versions
-+
+        of the standard, though I have not implemented any support for new
-+
+        geometry; approximations are substituted and warning messages issued.
-+
+        Unfortunately, this code is not tested, since I don't have any IES
-+
+        files that use these shapes.
-+
-+
+Added support for depth-of-field blurring in vwrays using -pd option.
-+
+Also, made -c count work with vwrays -i, producing multiple samples
-+
+per indicated pixel position.  At the same time, support for the -pd
-+
+option was added to rtpict, which calls on vwrays for its samples.
-+
-+
+Fixed issue with BSDFs that didn't obey reciprocity, where direct
-+
+sampling wasn't following exactly with indirect sampling.  This was
-+
+discovered and reported by Jon Sargent.
-+
-+
+Created checkBSDF tool to test XML BSDF reciprocity and perform similar
-+
+sanity checks.
-+
-+
+Added -O option to pvalue and pextrem to report watts/sr/m^2 even if
-+
+picture is XYZE.
-+
-+
+Made subtle changes to header i/o routines to preserve alignment in
-+
+binary file formats to enable memory-mapping.  Implemented memory-mapped
-+
+matrix loading in rmtxop for binary double files.
-+
-+
+Removed ambient value sorting, which was written when ambient caches
-+
+could overwhelm available memory.  This is rarely the case these days,
-+
+and the added code complexity and updating of cache values with LRU
-+
+counts dirties pages that would otherwise remain clean, so it was
-+
+often a loss even when VM was an issue.
-+
-+
+Added iso2klems script to compute a Klems BSDF based on specular
-+
+and diffuse measurements as a function of incident angle.
-+
-+
+Fixed issue with over-counting diffuse component during aBSDF
-+
+peak extraction.
-+
-+
+Added dctimestep -x and -y options to specify image dimensions
-+
+for multiple outputs corresponding to result vectors.
-+
-+
+Added -P option to rcalc to pass formatted input when cond is <= 0.
-+
-+
+Created rcrop utility for cropping matrices and pictures more
-+
+conveniently, correcting view information.  Expect it to be handy
-+
+for extracting rows and columns from matrices, mostly.
-+
-+
+Changed pcomb so -o option elides original exposure values
-+
+from indented source headers.
-+
-+
+Added getinfo -r option, which is similar to -a except it will
-+
+replace indicated lines with new ones.
-+
-+
+Slight change to vwrays -d option to not spit out "-ld-", and to
-+
+produce "-ld+" without requiring input picture as argument.
-+
-+
+Added automatic overture calculation to rtpict with -n > 1 if
-+
+ambient cache is on and file is named.  If straight image output
-+
+is requested, we randomize all samples and avoid cache collisions.
