Using WebGL via SDL, it would seem emscripten is pre-enabling vertex buffers 0 and 1 before my application code executes, this means when I use a shader that only takes one vbo it will return the error that vbo 1 has no data bound to it.

Emscripten pre-enables these buffers using the `emscripten_glEnableVertexAttribArray()` function in index.js where as my compiled application uses `_glEnableVertexAttribArray()`.
