<!-- ##### SECTION Title ##### -->
AtkValue

<!-- ##### SECTION Short_Description ##### -->
The ATK interface implemented by valuators and components which display or
select a value from a bounded range of values.

<!-- ##### SECTION Long_Description ##### -->
<para>
#AtkValue 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 #AtkObject representations which
implement #AtkValue on the component's behalf.  #AtKValues may be
read-only, in which case attempts to alter the value return FALSE to
indicate failure.
