Without peeking into this, it should be possible by: checking if the extension is in the
getSupportedExtensionslist and returning a truthy value; by defining the relevant constants; and by handling any special cases in the draw calls.Tests might be a different problem as they may or may not pass, even if the implementation is sound. Though, likely the current conformance suite should handle it.

I've checked on my newer build of angle with headless-gl, and the extension is there, seemingly by default. So I'm adding the bindings for it.

This is essentially my patch, but it isn't outputting anything to the textures, so opening an issue with Google Angle: https://github.com/proxy/gist.github.com/robertleeplummerjr/cce00202e08954cf8df512eed838de66
