commit c628c1e949766d4e3cd6cfad9fab7e648ec5e33a
Author: Roman Joost <roman bromeco de>

New interface for XMPModel-based gtkwidgets.
The new interface provides a common set of methods used by other gtk
widgets (e.g. GtkEntry). This interface is bound to the XMPModel
allowing writing/reading to and from the XMPModel utilised by the
widgets.
