Summary

0001093: Exphotonmap crashes with 0 direct photons

Description

If exphotonmap is set with directphotons = 0, it will crash as photon shooting finishes. This is a pretty rare case, it would likely only be used when all light sources are behind non-architecural glass and thus all lighting would be caustics. Still, the renderer should probably throw an error instead of just crashing.

Steps To Reproduce

1. Set direct photons = 0

2. Run the render. Photon shooting will progress fine, until all maps have filled. At this point, Lux will crash.
