%%%Brecht, can you please check this?%%%
%%%Developer note: issue seems to be because SSS preprocessing pass is do on non-antialiased buffer. The extra shading points near edges due to AA then don't have a sample nearby in the SSS point cloud, which cause more influence from the back.%%%
%%%Brecht: is this an active open issue on your list, or a known limitation of SSS approximation code, with possible bypasses?%%%
%%%It's sort of a known limitation of the current implementation, you start to get artifacts when the SSS scattering distance is too small because you'd need many points. Moved it to the todo list.
