2159 + =========================
2160 + Version 5.2
2161 +
2162 + Created psketch program to apply non-photorealistic rendering to selected
2163 + objects, identified by modifier name(s).
2164 +
2165 + Added '*' and '/' operations to rmtxop for element-wise multiplication and
2166 + division of same-sized matrices.
2167 +
2168 + Changed falsecolor so "-s" option is adjusted to match legend if one.
2169 +
2170 + Falsecolor legend changes and improvements by David G-M and Stephen W.
2171 +
2172 + Fixed bug in peak extraction code that generated
2173 + "Bad call to SDqueryTreProjSA" error, reported by Lars Grobe.
2174 +
2175 + Increased maximum luminance to 10^7 in pcond to fix issue noticed
2176 + by Axel Jacobs where veiling glare not added for the sun under
2177 + some conditions.
2178 +
2179 + Increased maximum number of open files in rcontrib to the system upper
2180 + limit of 2048 rather than the default 512 under Windows.
2181 +
2182 + Added top-level resources directory with files from Rob Guglielmetti.
2183 +
2184 + Improved accuracy for peaky BSDFs and small light sources.
2185 +
2186 + Fixed issue with pmapdump noted by Axel Jacobs.
2187 +
2188 + Improved accuracy of bsdf2ttree when converting scattering interpolation
2189 + representatons with strong peaks.
2190 +
2191 + Tweaked peak-extraction code to work more reliably.
2192 +
2193 + Georg Mischler updated SCons build system.
2194 +
2195 + Rob Guglielmetti and Alex Swindler updated CMake build system.
2196 +
2197 + Modified pcomb so the first view seen in the inputs is written into header.
2198 +
2199 + Wrote rtpict script to run rtrace in parallel mode and simulate rpict with
2200 + -n option.
2201 +
2202 + Added ability to move forwards/backwards specified distance in rvu "origin"
2203 + command.  Feature requested by John Mardaljevic, who essentially owns this
2204 + command, now.
2205 +
2206 + Reduced bias in ambient super-sampling method.
2207 +
2208 + Fixed bugs associated with zero transmission in chromatic tensor trees.
2209 + Thanks to Lars Grobe for pointing out issues.
