Add GtkAccessibleValue All accessible properties and states may have one of the following types: - true/false - true/false/undefined - true/false/mixed/undefined - reference (to another UI element) - reference list - integer - number (real numerical value) - string - token (one of a limited set of allowed values) - token list See: https://www.w3.org/WAI/PF/aria/states_and_properties#propcharacteristic_value The GtkAccessibleValue is a simple reference counted type that can be "subclassed" to implement each value type. This initial commit adds GtkAccessibleValue and the basic subclasses for plain boolean, tristate (true/false/undefined), and token types, including statically allocated values that can be shared instead of allocated.

GError **error);
Plumb all the GtkAccessibleProperty values into GtkAccessibleValue Similarly to how we deal with GtkAccessibleState.

Add GtkAccessibleValue All accessible properties and states may have one of the following types: - true/false - true/false/undefined - true/false/mixed/undefined - reference (to another UI element) - reference list - integer - number (real numerical value) - string - token (one of a limited set of allowed values) - token list See: https://www.w3.org/WAI/PF/aria/states_and_properties#propcharacteristic_value The GtkAccessibleValue is a simple reference counted type that can be "subclassed" to implement each value type. This initial commit adds GtkAccessibleValue and the basic subclasses for plain boolean, tristate (true/false/undefined), and token types, including statically allocated values that can be shared instead of allocated.
