WebGL in WebAssembly with AssemblyScript.

This is a work-in-progress port of Three.js, a JavaScript 3D WebGL library, into AssemblyScript.

It'd be sweet to have a high-performing WebGL engine that runs in the web via WebAssembly and is written in a language that web developers are already familiar with: JavaScript, in the form of TypeScript (a superset of JavaScript with types).

Enter AssemblyScript, a toolchain that allows us to write a strictly-typed subset of TypeScript code and compile it to WebAssembly (an assembly-like language representing machine code) for speed.
