It should now be possible to compute many bounces with -aa 0, which used to be prohibitively expensive. + +Added -T option to xshowtrace to trace rays to light sources. + +Added meta2bmp program to produce BMP files from metafile graphics. + +Added cct_x(t) and cct_y(t) to src/cal/cal/blackbody.cal to interpolate +CIE chromaticities for particular black-body temperatures. + +Increased maximum number of input pictures in pcomb and pcompos to 512. + +Created rtcontrib program for computing ray contribution coefficients. +This tool may be used to do standard optical ray tracing or daylight +coefficient calculations for annual simulations, among other uses. + +Added tilde ('~') output option as part of the -o* specification of +rtrace. This permits ray trees to be parsed more easily in binary +output mode, as needed by rtcontrib. + +Implemented Russian roulette ray termination with -lr <= 0. +Made -lr -10 the default in rtcontrib. + +Made rtcontrib -f option search RAYPATH directories. + +Made it so -o option of rtcontrib can pipe -o output to a command. + +Added -if and -of options to total for binary i/o (following rcalc mold). + +Switched default options in rtrace to use Russian roulette. (Rpict and rvu +still use biased ray termination.) + +Added rtcontrib -r option to recover partial output. + +Added -R rendering option for pure Monte Carlo sampling. +(Got rid of -DMC compile option, whicht his makes superfluous.)
