The config matched by visual ID will have the right fbconfig ID set, you
don't need to go looking for it, so long as you look in the list of
fbconfigs as opposed to the list of visuals (which do not have
GLX_FBCONFIG_ID filled in).
It's sort of broken that we have two lists here, when the only real
distinction is that glXChooseVisuals needs to filter out non-window-
capable configs from its view. That's a bigger cleanup for another day.
