Thank you, it's nice to write OpenGL code in Javascript, but if you're going to write a plugin that lets JavaScript access OpenGL then please don't rewrite the entire OpenGL API.
From what I see from the documenation this is not an OpenGL wrapper. First it wraps OpenGL and DirectX. Then it also seems to be shader based, so it seems to be less a rewrite of OpenGL, but more a rewrite of GLSL. They describe in the FAQ why they didn't use GLSL itself.
