This should be implemented for components which either display a value from a bounded range, or which allow the user to specify a value from a bounded range, or both. For instance, most sliders and range controls, as well as dials, should have Atk::Object representations which implement Atk::Value on the component's behalf. Atk::Values may be read-only, in which case attempts to alter the value return false to indicate failure.
