Fix #114634: correlated samples in volume when using equiangular sampling and light tree

Reuse point light (with soft falloff) position doesn't work when we restrict the equiangular sample range wrt the sampled position, the result is biased because the oriented disk is only partially…

Fix #114634: correlated samples in volume when using equiangular sampling and light tree

Reuse the sampled light position would make it easier for equiangular sampling to compute the valid range, not sure if it would be noisier or cause fireflies near the light source, I can also give…

Fix #114634: correlated samples in volume when using equiangular sampling and light tree

I'm not sure I like this solution, but it's the first one I got working without bias (except for the aforementioned TODOs). A potential problem is that the result might be noisier when the light…
