1963 * Command line parsing in this function is rather fiddly,

1966 * can't open an X display, whereas in fact we want to permit
1967 * our --generate and --print modes to run without an X
1968 * display.
1969 *
1970 * So what we do is:
1971 * - we parse the command line ourselves, without modifying
1972 * argc/argv
1973 * - if we encounter an error which might plausibly be the
1974 * result of a GTK command line (i.e. not detailed errors in
1975 * particular options of ours) we store the error message
1976 * and terminate parsing.
1977 * - if we got enough out of the command line to know it
1978 * specifies a non-X mode of operation, we either display
1979 * the stored error and return failure, or if there is no
1980 * stored error we do the non-X operation and return
1981 * success.
1982 * - otherwise, we go straight to gtk_init().
