That, or having a dirty flag would work as well. I think we should
have a structure describing each value:

    struct config_param {
        const char *name;
        void *value; /* or we can have a union here */
        int dirty;
        const char *flyby_help;
        HWND control;
        /* etc, etc. */
    }

    On "Apply", we can simply walk the list and commit all
    things that are dirty. In general, I think it will be
    helpful going forward to be able to have such a thing
    in place so we can easily associtate metadata with each
    value.
