 Added rxpict rendering tool based on C++ RpictSimulManager class.
 Multi-processing and spectral output are supported.
 
+Wrote rxpiece tool that will render pictures using tiling and
+can handle different output formats and hyperspectral pictures.
+Only runs on a single machine, however -- now NFS locking on
+shared volumes.  Mainly a demonstration tool for RpictSimulManager
+C++ class, but may have its uses.
+
+Fixed a bug in BSDF sampling of sources pointed out by
+David Geisler-Moroder, which tended to overestimate specular
+contributions for some BSDFs.

 Added crude ability to read and convert spectra to RGB in ximage,
-ra_bmp, and ra_rgbe programs.  Also updated fast tone-mapping
-library to handle spectral HSR inputs at the same time.
+ra_bmp, ra_ps, and ra_rgbe programs.  Also updated fast tone-mapping
+library to handle spectral HSR inputs at the same time.  HSR
+input handling was added in a similar fashion to pcond and pvalue
+for convenience.
+
+Added handling of hyperspectral images to normtiff, a handy program
+for quickly tone-mapping Radiance RGBE, XYZE, and now hyperspectral
+pictures, as well as IEEE float or LogLuv TIFFs.
+
+Added handling of hyperspectral pictures to pextrem, though
+results are still reported in RGB.
+
+Added accurate conversion of hyperspectral pictures to ra_xyze.
+
+Added hyperspectral picture conversion to ra_tiff, with accurate
+color when targeting 16-bit/comp., LogLuv, and float utput,
+and the approximate method for 24-bit RGB.
