Use GdkFrameClock for the timing of GtkTimeline. This require the user to provide either a GtkWidget or a GdkFrameClock when creating the timeline. The default constructor now takes a GtkWidget. If you want to create a GdkFrameClock without a widget, you need to use g_object_new() and pass in a GdkFrameClock and GdkScreen. https://bugzilla.gnome.org/show_bug.cgi?id=685460
