Unfortunately I have been unable to find the deleteContext function in the canvas API. Some implementations keep webGL contexts around even after all references are set to null. The WEBGL_lose_context extension seems to be the only way to declare you are finished with a context and free the context resource itself in a deterministic manor.

This deliberately isn't specified. If you're looking for a way to free your application's resources, you should use the various delete* APIs.

It says the extension “WEBGL_lose_context” simulates webgl context loss. Does it mean the browser actually frees the resources on the GPU allocated by the webgl context or just pretends that it did?
