Gets a style property from context for the given state.
Note that not all CSS properties that are supported by GTK+ can be
retrieved in this way, since they may not be representable as gobject.Value
GTK+ defines macros for a number of properties that can be used
with this function.
Note that passing a state other than the current state of context
is not recommended unless the style context has been saved with
Style.contextSave.
When value is no longer needed, Value.unset must be called
to free any allocated memory.
