It seems to me that the GtkAdjustment API maps very well onto
AtkValue, but I think that as you said GtkAdjustment is an internal
data member of certain GtkWidget types...

It might still be useful to subclass AtkObject (not GtkAccessible) for
GtkAdjustment, but there might not be a corresponding factory
implementation... the idea being that once AtkValue is implemented for
GtkAdjustment, any GtkWidgets that use GtkAdjustment internally could
easily delegate their AtkValue implementation to the GtkAdjustment
implementation.
