PBR is for 3D stuff. It's nice to not need it. We'll want to clean up our view conversion definitions in the future. Co-Authored-By: Miguel Albernaz <albernazmiguel@gmail.com>
The resulting texture isn't used yet, but it's being written to. Co-Authored-By: Miguel Albernaz <albernazmiguel@gmail.com>
Now we're using our light map, blended with our main texture. Co-Authored-By: Miguel Albernaz <albernazmiguel@gmail.com>

Not strictly necessary, but I do like having an explicit render graph, especially if it's something someone else ever wanted to tweak. Co-Authored-By: Miguel Albernaz <albernazmiguel@gmail.com>
This will allow us to sanely expand our API as we introduce more occluder shapes. Co-Authored-By: Miguel Albernaz <albernazmiguel@gmail.com>
A refactor, again getting us to a world of a proper render graph. Co-Authored-By: Miguel Albernaz <albernazmiguel@gmail.com>

Nice to split this one up, rather than all the textures living on one component. Co-Authored-By: Miguel Albernaz <albernazmiguel@gmail.com>
Now we can completely isolate our light map and sdf textures. Co-Authored-By: Miguel Albernaz <albernazmiguel@gmail.com>
This shader isn't specific to any one pipeline, so let's pull it up. Co-Authored-By: Miguel Albernaz <albernazmiguel@gmail.com>
