--- Comment #13 from Henri Verbeet hverbeet@gmail.com 2012-04-02 15:28:42 CDT --- If this is the first time glGetString(GL_EXTENSIONS) is called there may not be much we can do at all. If internal_gl_extensions is already initialized you can probably return that, but even in that case it seems somewhat questionable to call glGetString() without a current WGL context.
