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. + +****** COMPATIBILITY CHANGE ******** +Introduced new Hessian-based error control in irradiance caching (ambient) +calculation. Since the format of the stored ambient values is different, +the old files will be rejected with an error message and must be removed. +The programs may be compiled with the -DOLDAMB option if this is a problem.
