The hope is that this function makes it easier to extend the font settings with more flags without having to add a function for every setting. A new flag for enabling hinting has been added. If set, this changes the font options on the global PangoContext and any newly created PangoContexts. The options are only set if the flag is changed from the default so it won't override any detailed setting chosen by the backend.
