Constant used to determine when the accessibleStateSet property has
changed. The old value will be the old AccessibleState and the new
value will be the new AccessibleState in the accessibleStateSet.
For example, if a component that supports the vertical and horizontal
states changes its orientation from vertical to horizontal, the old
value will be AccessibleState.VERTICAL and the new value will be
AccessibleState.HORIZONTAL. Please note that either value can also
be null. For example, when a component changes from being enabled
to disabled, the old value will be AccessibleState.ENABLED
and the new value will be null.
