2714   Added rxpict rendering tool based on C++ RpictSimulManager class.
2715   Multi-processing and spectral output are supported.
2716  
2717 + Wrote rxpiece tool that will render pictures using tiling and
2718 + can handle different output formats and hyperspectral pictures.
2719 + Only runs on a single machine, however -- now NFS locking on
2720 + shared volumes.  Mainly a demonstration tool for RpictSimulManager
2721 + C++ class, but may have its uses.
2722 +
2723 + Fixed a bug in BSDF sampling of sources pointed out by
2724 + David Geisler-Moroder, which tended to overestimate specular
2725 + contributions for some BSDFs.
2726 +
2727   Added crude ability to read and convert spectra to RGB in ximage,
2728 < ra_bmp, and ra_rgbe programs.  Also updated fast tone-mapping
2728 > ra_bmp, ra_ps, and ra_rgbe programs.  Also updated fast tone-mapping
2729   library to handle spectral HSR inputs at the same time.  HSR
2730 < input handling was added in a similar fashion to pcond and pvalue.
2730 > input handling was added in a similar fashion to pcond and pvalue
2731 > for convenience.

2733 > Added handling of hyperspectral images to normtiff, a handy program
2734 > for quickly tone-mapping Radiance RGBE, XYZE, and now hyperspectral
2735 > pictures, as well as IEEE float or LogLuv TIFFs.
2736 >
2737 > Added handling of hyperspectral pictures to pextrem, though
2738 > results are still reported in RGB.
2739 >
2740 > Added accurate conversion of hyperspectral pictures to ra_xyze.
2741 >
2742 > Added hyperspectral picture conversion to ra_tiff, with accurate
2743 > color when targeting 16-bit/comp., LogLuv, and float utput,
2744 > and the approximate method for 24-bit RGB.
2745 >
2746 > Taoning added genssky -L option to specify global and diffuse
2747 > illuminance values for output calibration.
2748 >
2749 > Created C++ class for rcontrib and example tool rxcontrib, which
2750 > is an optional compile in the src/rt directory.  The output
2751 > model is more general in some respects and the operations more
2752 > efficient, but standard output is not supported, nor is ASCII
2753 > results data.
2754 >
2755 > Added experimental source-skipping method to rpict for scenes
2756 > with large number of light sources.  Currently works with
2757 > rcontrib and separate srcsamp image-processing tool.  Controlling
2758 > rpict options are -dS for skip bitmap specification and -dC
2759 > for correction coefficient image.  Compile using -DSSKIPOPT
2760 > to include this option.
2761 >
2762 > Added strnstr.c compatibility module in ray/src/common, since
2763 > it isn't present on Linux-derivatives.
2764 >
2765 > Added WGMDfunc material type with programmable roughness and
2766 > separate modifier paths for the different components.
