fix: ratmain renamed to rxmain

refactor: minor code improvements

chore: better error detection if ed fails to build Version.c

Moved findmaterial() from source.c to initotypes.c

Added AR variable to provide a way to override standard library builder

Made proximity test (plugaleak) more robust with transparent surfaces, etc.

Separated creation from use of contribution photon maps

Initial import of ooC photon map

Added Version.c updating with new photon map sources

Initial check-in of photon map addition by Roland Schregle

Changed sampling to use Hilbert curve as suggested by Lars Grobe

Added ashik2 type for anisotropic Ashikhmin-Shirley BRDF model

Moved source initialization

Reworked rtcontrib into rcontrib program

Minor fixes and adjustments

Added checknorm() macro to avoid normalization errors with gcc --fast-math

Added -n option to rtrace and moved quit() funciton out of raypcalls

Added -n option to rvu for multiple rendering processes

Compiler warning fixes for Linux release (thanks to Bernd Zeimetz)

Removed NICE macro settings, as this slows programs unduly under some OS's

Added Russian roulette ray termination and fixed ambient weights & measures

Removed unused programs and files from distribution (sources to CVS attic)

Hopefully, a final fix to the illum drawing problem -- ignore them

ANSI-discovered fixes thanks to Schorsh

Added shadow casting algorithm and separated occlusion cache routines

Replaced all calls to vfork() with regular fork() calls

Move all libraries to ../lib on build (not just on install).

Broke standard.h into rtio.h, rterror.h, rtmath.h, and rtmisc.h

Changed alias handling to allow tracking, fixed freeobjects() and do_irrad bugs
