 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.
