The main goal is to implement a GPU driven renderer for Godot 4.x. This is a renderer that happens entirely on GPU (no CPU Dispatches during opaque pass).
Additionally, this is a renderer that relies exclusively on raytracing (and a base raster pass aided by raytracing).
It is important to make a note that we dont want to implement a GPU driven renderer similar to that of AAA/Unreal, as example.

| # Loads a scene in the background using a seperate thread and a queue. | |
| # Foreach new scene there will be an instance of ResourceInteractiveLoader | |
| # that will raise an on_scene_loaded event once the scene has been loaded. | |
| # Hooking the on_progress event will give you the current progress of any | |
| # scene that is being processed in realtime. The loader also uses caching | |
| # to avoid duplicate loading of scenes and it will prevent loading the | |
| # same scene multiple times concurrently. | |
