it's bad:

also, thread group size = 16, 8, 1, wave64

rtx: better surface light triangle selection
...
- Enumerate all triangles and pick random one based on solid angle/expected contribution
- Sample N(4) of surface lights per pixel/frame. This is needed for performance reasons. Some surface lights have way too many triangles and enumerating them takes ages.
- Write emissive color directly on primary ray hit (still looks too bright ;_;)
Known issues:
- changes above make it really apparent that light clusters are subtly broken (see test_brush3, etc)
- triangle contribution sometimes breaks at axis aligned plane intersecting one of the vertices
(supposedly the solid angle is broken?)
- performance is bad
