Sure.  We can either remove x_gtk_use_window_move and call
gtk_window_move unconditionally or leave x_gtk_use_window_move alone and
call gtk_window_parse_geometry only if GTK_CHECK_VERSION permits it.

Have these already been deprecated with GTK 3.10.8?  I'm using 3.4.2
here.  In any case please post a list of these functions here (unless
you intend to take care of them by yourself).

Thanks, martin
