It's unlikely that anyone will want to have, say, a GtkWidget that also acts as a GdkFrameClock, so an abstract base class is as flexible as making GdkFrameClock an interface, but has advantages: - If we decide to never make implementing your own frame clock possible, we can remove the virtualization. - We can put functionality like history into the base class. - Avoids the oddity of a interface without a public interface VTable, which may cause problems for language bindings.
