Progressive Lightmapper


Steps to reproduce:

1. Download CornellBox project and open CornellBox scene (more details in the comments)
2. Make sure that Progressive Updates flag is enabled
3. Bake the lighting using either CPU or GPU lightmapper
4. Pay close attention to the directionality within the lightmap, especially in indirect areas
5. Wait for the bake to finish
6. Notice how the final result has less pronounced directionality


- Affects both CPU and GPU lightmappers
- Affects all render pipelines
- Lighting settings have no effect on this
- Only affects directional mode
