This function may be called at any time, even before SDL_Init(). This makes it useful for reporting errors like a failure to create a renderer or OpenGL context.
On X11, SDL rolls its own dialog box with X11 primitives instead of a formal toolkit like GTK+ or Qt.
Note that if SDL_Init() would fail because there isn't any available video target, this function is likely to fail for the same reasons. If this is a concern, check the return value from this function and fall back to writing to stderr if you can.
