We can't change the default behavior of gtk_init() because
a lot of people are presumably assumming that it is going
to abort on failure. However, I think we could do:

Either 

 void gtk_set_abort_on_error (gboolean abort);

Or, (perhaps better)

 gboolean gdk_check_init (int *argc, char ***argv);
