Shadows from emissive maps?

If realtime or baked GI is enabled emissive materials* will affect the nearby geometry and will be shadowed. The shadowing from emissive materials is inherent in the solution as each output texel knows which parts of the scene it sees.

That currently happens at the precompute resolution for both realtime and baked** lightmaps.

*) E.g. a material that uses the Standard shader and has non-black emission.
**) For baked lightmaps it will be done at baked resolution relatively soon, which will give a much more accurate penumbra and contact shadows from emissive materials, sky light and bounced light.
