GtkSharp/gtk/NodeCellDataFunc.cs
Mike Kestner bd50999b1b 2005-03-12 Mike Kestner <mkestner@novell.com>
* generator/CallbackGen.cs : don't derive Wrappers from DelegateWrapper
	any more.  It leaks delegates like crazy. We effectively now use call
	scope as the default for delegate parameters.
	* generator/MethodBody.cs : use new simpler Wrapper ctor.
	* glib/DelegateWrapper.cs : mark the ctor obsolete so people know to
	update any manually coded wrappers out there.
	* */*.custom : use new simpler Callback Wrapper ctors.
