/**

/**

 * InverseBindingListener, see DocumentView or LayerListView's currentLayer 2-way binding
 * (along with the InverseBindingMethod declarations in DocumentViewModelBindingAdapters).
 *
 * @param view                   The view we're 2-way binding to.
 * @param onHueChangeListener    The OnHueChangeListener bound by the developer on the view
 *                               in question.
 * @param inverseBindingListener Synthetic attribute representing an InverseBindingListener
