feat: Added new WGMDfunc programmable material
fix: improvement to blocker test
fix: Improved tracking of reflected vs. transmitted rays for antimatter
Added MAX2SHADE macro to limit precheck time for source obstructions.
Fixed bug in source obstructor cache for antimatter
Eliminated a number of minor warnings (all innocuous)
Added clearing of clipped object (antimatter) when sources freed
Created RNUMBER type (#define) in preparation for 64-bit compiling
Compiler warning fixes for Linux release (thanks to Bernd Zeimetz)
Fixed bug in shadow cache related to antimatter holes
Extensive changes to enable rtrace -oTW option for tracking ray contributions
Fixed Mark Stock's abort error caused by source & mist combination

Fixed bug spotted where spheres with sources inside were blocking themselves
Made it so obstructor cache is only initialized once with parallel processes
Made source obstructor cache initialization more robust
Added local caching of obstruction index
Added isopaque() macro to otspecial.h
Continued ANSIfication. There are only bits and pieces left now.
Bug fix in source substructuring test and added debug bounds checking
Renamed rview, lam, calc, and neat to rvu, rlam, icalc, and neaten
