/** %Gdk::DragSurfaceImpl is a Gdk::Surface that implements the Gdk::DragSurface interface.
 *
 * The GdkDragSurface interface can be implemented by C classes that
 * derive from GdkSurface. No public GTK class implements GdkDragSurface.
 * Some GTK functions, such as gdk_drag_get_drag_surface(), return an object
 * of a class which is derived from GdkSurface and implements GdkDragSurface.
 * Since that C class is not public, it's not wrapped in a C++ class.
 * A C object of such a class can be wrapped in a %Gdk::DragSurfaceImpl object.
 * %Gdk::DragSurfaceImpl does not directly correspond to any GTK class.
 *
 * This class is intended only for wrapping C objects returned from GTK functions.
