perf: Eliminated redundant tests
feat(rpict,rtrace,rvu,rxpict,rxtrace,rxpiece): Added -e expr and -f file.cal options
fix: Added check for empty subfeature that could cause memory read-past-end
fix(rpict,rtrace,rcontrib,rvu): Fixed bug in feature sublist check
fix(rpict,rtrace,others): Fixed parsing of '-cw' parameter
fix: multiple bug fixes in hyperspectral code, added rvu, mkillum, rsensor, and ranimove to "working except photon map" status
fix(rcontrib): Removed participating media from rcontrib -features
fix: tighter requirements on subfeature list
fix(rcontrib): removed AdaptiveShadowTesting from feature list (didn't belong)
feat(rpict,rtrace,rcontrib): Added -features option to check for method support
Improved error-checking for too many words in file or string
newer C++ compilers have a standard type named "bool". rename macro to get rid of warnings.
Initial check-in of photon map addition by Roland Schregle
Eliminated unnecessary "extern" and "register" modifiers
Changed -sj option to -ss and added multiple specular sampling
Made -u+ option truly random
Changed wording in -defaults output (again)
Changed wording on -defaults output
Had to change new -R rendering option to -u to avoid conflict with rpiece
Added -R option for pure Monte Carlo rendering, replacing -DMC compile option
Added Russian roulette ray termination and fixed ambient weights & measures
Fixed error message for missing -aE and -aI files
Added savqstr() calls on recorded strings, which might be on stack
ANSI-discovered fixes thanks to Schorsh
Continued ANSIfication. There are only bits and pieces left now.
Changed (char *) casts for memory copies to (void *) and other fixes
Replaced inline copyright notice with #include "copyright.h"
