 utilities consistent with other tools in Radiance.
 
 Added triangulation routine to handle convex polygons in obj2mesh.

+****** COMPATIBILITY CHANGE ********
+Made backface visibility apply to all material types, including
+transparent and translucent materials (except dielectric and interface).
+This makes the option useful in cases where adjacent trans surfaces
+are placed next to each other by a modeler that only understands
+volumetric objects.
+
+Changed dctimestep so that output matrices (-n > 1) are preceded by a
+header, and added support for float and double output formats with -o[fd].
+
+Introduced eplus_adduvf program to compute user view factors for EnergyPlus.
+
+Changed image-plane sampling in rpict to use Hilbert curve, which gives
+less of a brushed/striped appearance to output pixels with -u- (default).
+
+Added ltview and ltpict Perl scripts contributed by Axel Jacobs, inspired
+by Rob Guglielmetti.
+
+Added header variables for NROWS, NCOLS and NCOMP to help standardize
+matrix files.  This functionality has been incorporated into
+rcollate, gendaymtx, and dctimestep.
+
+Created rmtxop utility to operate on multi-component matrices.  This
+facilitates some daylight matrix calculations, and provides a general
+tool for manipulating matrix data.
