fix: removing dependency on geometry in WebGLRenderer

Fixes -> #165

This looks pretty good.

A few questions I have:

• Why did you remove the dependency of Plane? This seems like an unneeded duplication of that logic.
• How much effort would it take to have a special case for border-radius of a DOM element so that we can use custom shaders to make the cutouts non-rectangular? I think this is something we have all known the limitations of but I am starting to think that we should prioritize this a lot higher.

1. Removed actual geometry from WebGL geometry because we are running into the same issue with browserify and require statements in the worker thread incrementing seperate counters for geometry Ids. -> DynamicGeometry renders different results in Web Workers #165
2. Border radius is definitely something we could do, I'd imagine it'd be some custom shader logic to discard some pixels based on border-radius but we should all talk about it if it is indeed a priority.
