 spectral sampling is enabled, but we will fix this as soon as possible.
 Calculation overhead appears to be approximately 10-15% for RGB
 renderings compared to version 5.4a.

+Added spectral rendering to rvu as well, and made -cs and -cw
+options standard across the rendering library.  I also brought
+mkillum, ranimove, rsensor, and mksource into the fold.  These
+tools were broken in the initial release.  (Hopefully, they are
+working now, but none have been tested as yet.)
+There was also an indexing bug in the spectral->RGB conversions
+that made reds into blues and vice versa, which has been fixed.
+
+Added i/o for spectral pictures to rmtxop, the first program that can
+ingest them.  (Only rtrace, rcontrib, and rfluxmtx can render them.)
+New symbolic rmtxop -c options, such as RGB, XYZ, S (for scotopic)
+and M (for melanopic) make color conversions simpler.  Alternatively,
+a reference matrix or picture may be given and the color space of
+that file will be used.  The -C option takes either a symbolic
+color space or reference file and is "sticky," so it applies to
+all subsequent input files that do not have their own -c right ahead
+of them.
+
+Added spectral picture support to rcrop and radcompare.
