I believe [program,location].toString() will result in the string
"[object WebGLProgram],[object WebGLUniformLocation]", as far as I
know. So you won't be able to use [program,location] as a unique key
in an object.

I'm currently using a trick like this to index by shader program...

    shaderProgram._glquery_id = shaderProgramCounter;
   locations[shaderProgram._glquery_id] = { uniforms: [...],
vertexAttributes: [...] };

...which works because you can only ever get a single instance of a
WebGLProgram by calling createProgram - there's no other way to
enumerate programs using the WebGL API.
