Cycles: Refraction ray bent depending on geometry density

I agree this is an issue with modeling, namely how the normals are computed.

With geometry node UV sphere, the vertex normals are computed purely from the vertex positions in `calculate_sphere_v…

Fix #120119: Area lamp artifacts in Cycles with light trees

I believe changing sc->N to sd->N is the correct fix, as this normal must be consistent for both forward tracing and NEE, and in NEE sc->N is not available.

Fix #120119: Area lamp artifacts in Cycles with light trees

First, the g < 0 condition is not checking whether a shading normal points inside the mesh, but whether the incoming light is below the geometry normal.
