Initializes the GDK library and connects to the windowing system.
If initialization fails, a warning message is output and the application
terminates with a call to exit(1).
Any arguments used by GDK are removed from the array and @argc and @argv
are updated accordingly.
GTK+ initializes GDK in gtk_init() and so this function is not usually
needed by GTK+ applications.
