Not required: you can easily create an accessible object for each meter,
whether it has a corresponding drawable or not.  The meters don't
even have to have GObjects associated with them, though it'd be easier
if they did.

The trick is to override get_n_children and ref_child in the parent 
container, then return the AtkObjects constructed for the "meters"
(whatever they are, as I said they don't have to be structures or
objects of any particular type).
