I refactored the Light Frog code from 11.311 LOC down to 3.248 LOC, sacrificing just cookies (don't need them), glow + tonemapping (things I'll do myself), ambient probes (don't need them), pipeline rebuilding (will be added later again) and model normal maps (I don't need them) ... and still not finished yet. I plan to merge the lighting with pre-calculated lightmaps, Unity style.

Directional sunlight (blueish) + Point light (red) + Spot light (green)
