1382   Fixed bug that caused incorrect reporting of non-surface in set when

1385 > Fixed inaccuracy in calculation of diffuse transmission in the presence
1386   of pure specular (Fresnel reflection) using "trans" material.  Thanks

1493 +
1494 + Fixed Russian roulette ray termination, which was doing the opposite of

1498 + Changed mksource to use 98th percentile (rather than 99th) for threshold.
