Cycles: include more transparency and emission in fast GI approximation
For indirect light rays, don't assume any hit is opaque, rather if it has
transparency or emission do the shading but don't do any further bounces.
Naturally this is slower when there are transparent surfaces, however
without this cutout opacity doesn't give sensible results.
