50200262df rtx: slightly improve black outlines on studio models (see #48) 
The core of the issue is that there are backfacing interpolated normals, NdotL and/or NdotV end up being negative for them.
Things we tried:
1. Explicitly using geometry normals for some things. Doesn't really work that well.
2. Clamping NdotX to some small value instead of just ignoring light contribution. Works better, but there are still some artifacts.

9c330e4118 add brdfs for lights 
Just straight copy-paste CC brdf header from Ray Tracing Gems 2 chapter
14.
Use these brdfs for direct lighting.
