WASM can access the GPU via middle layers like SDL. I.e. you can write a C program that uses opengl and compile it and as long as you include the right flags etc into `emcc` you will barely need to touch or glue it together on the JS side at all.

All those go through JS as far as I'm aware. Emscripten bridges everything for you, but technically it goes through JS so SDL's calls also go through JS.

You're correct but I don't see why that matters. From your perspective as a C coder you get webgl access without having to write JS, that's what's important. Everything is "mixed together" into asm in the end anyway whether it's glue code in JS or browser side glue code.
