[WIP] WebGLRenderer

[trusktr]

What a pain! But! I'm learning Three.js internals, and it will be rewarding to see this thing output visuals!

@copilot merge main into this WebGLRenderer branch and resolve the conflicts. Then Continue this working porting over the WebGLRenderer from Three.js r125 (0.125.0 on npm). Please feel free to look at the Three.js repo, and also look around the repo here to see patterns, how to write test files, and look at package.json to learn how to run tests.

The repo does not have a lock file, so hopefully things still work. Please unignore lock files in .gitignore and commit a lock file after npm install, then from then on use npm clean-install.
