- And this right here is why ye olde tiled lighting would never fly in Tiny Glade :D (build by Omayli)

- In our next Tiny Glade update we'll bump the light limit from 32 to 32k while keeping the cost more or less the same. The small limit has been a cop out, as we didn't quite know how to render huge numbers of (screen-space) shadow-casting lights without severe performance degradation.
- Initially, I tried ReSTIR, but I didn't quite enjoy that even with a single light source it still produced noise. For our specific case it was kinda silly; I'd do all this complicated machinery just to end up denoising a known quantity.
- So I figures, why not just look up the light IDs stored in reservoirs and use them directly, ignoring the computed contribution weights? This way there's no noise from ReSTIR, and you don't need to be careful with resampling to avoid pretty terrible halo artifacts and/or crawling temporal noise.
