2644   Added spectral picture support to rcrop and radcompare.

2646 < Added new utility, rmtxcomb, which is hard to type and hard to

2649   like those in pcomb for putting matrices together, working on
2650   an element at a time.  (No resizing of matrices or accessing

2654   provide for a single matrix-multiplication operation at the end,
2655   which only requires memory for that final matrix.
2656 +
2657 + Added support for filtering hyperspectral images to pfilt.
2658 +
2659 + Added support for 1- and 3-component float matrix i/o to
2660 + pcomb to allow for better interoperability.
2661 +
2662 + Added support for -co+ option to rtpict, so it can directly
2663 + produce hyperspectral images.
2664 +
2665 + Added new "specdata" and "specpict" primitives to support
2666 + interpolated spectral data files and hyperspectral images
2667 + as patterns.
2668 +
2669 + Added support for multispectal sampling in rsensor, which will
2670 + put out as many color channels as specified in any -cs option
2671 + (default is 3 for RGB).
2672 +
2673 + Added ability of mgf2rad to convert spectral data at least
2674 + for light, glow, plastic, and metal primitive types.
