 /**
  * @brief The Client which gets decorated.
  *
  * The DecoratedClient provides access to all the properties relevant for decorating the Client.
  * Each DecoratedClient is bound to one Decoration and each Decoration is bound to this one
  * DecoratedClient.
  *
  * The DecoratedClient only exports properties, it does not provide any means to change the state.
  * To change state one needs to call the methods on Decoration. This is as the backend might
  * disallow state changes. Therefore any changes should be bound to the change signals of the
  * DecoratedClient and not be bound to state changes of input elements (such as a button).
