Godot Shader System Proposal

Godot 4's current shader/PSO system assumes the following:

1. Specialization Constants reduce compilation time (true) but are not free.
2. Specialization Constants are well optimized by Driver (blatantly false on Android),
3. Uniform Static branches are free. They're very cheap but I am seeing incremental improvements when removed entirely via #ifdef. Sometimes major improvements.

Godot 4 wants these assumptions to be true because they help reduce the number of shader & PSO variants, which are key to reducing compilation stutter.

What this proposal is about

• Creating a Compositor that will handle rendering and compute
• Make ordering tasks around MUCH easier
• Fixing barrier problem

What this proposal isn't

• It's not about exposing the Compositor to the user
