Some good news.

This is indeed good news. Now all that is missing is allowing a scene in a 64bit doubles world to be rendered down to a 32bit representation for the GPU IIRC. This may be possible to do in GDScript using familiar techniques like origin shifting and dynamic camera clipping to improve depth buffer usage.

I might give this another go using the current state of double support. The previous attempt with the then half-baked support wasn't quite successful yet.

On rendering, I believe it is being discussed here godotengine/godot#58516
