* gtk/Makefile.am : add new file. * gtk/glue/makefile.win32 : add missing file. * gtk/NodeCellDataFunc.cs : new callback delegate type and marshaler for NodeStore tree views using GtkTreeCellDataFuncs. * gtk/NodeStore.cs : add internal GetNode overload by TreeIter. * gtk/NodeView.cs : add AppendColumn overload that uses data funcs. * gtk/TreeViewColumn.custom : manual implementation for SetCellDataFunc to support both TreeIter and ITreeNode models. We need to hold a ref to a delegate for each cell renderer on a column. [Fixes #63062] * sample/NodeViewDemo.cs : use a NodeCellDataFunc for one of the cell renderers in the tree. svn path=/trunk/gtk-sharp/; revision=37904
