Thanks for the quick fix on that!  It works great.

What I mean is I have code like this (makes a control have a minimum size),
which is shared code for all controls:

	Control.SizeRequested += (o, args) => {
		var alloc = args.Requisition;
		alloc.Width = Math.Max (alloc.Width, MinimumSize.Width);
		alloc.Height = Math.Max (alloc.Height, MinimumSize.Height);
		args.Requisition = alloc;

To do this with gtk# 3, I'd have to subclass each control:

	class MyNotebook : Gtk.Notebook
		public Gdk.Size MinimumSize { get; set; }

		protected override void OnGetPreferredHeight (out int minimum_height, out
int natural_height)
			base.OnGetPreferredHeight (out minimum_height, out natural_height);
			minimum_height = MinimumSize.Height;

		protected override void OnGetPreferredWidth (out int minimum_width, out
int natural_width)
			base.OnGetPreferredWidth (out minimum_width, out natural_width);
			minimum_width = MinimumSize.Width;

It would be nice to have corresponding event(s) for the new
GetPreferredWidth/Height apis (as well as OnAdjustSizeAllocation,
OnAdjustSizeRequest, etc), so one could do something like this:

	Control.PreferredHeightRequested += (o, args) => {
		args.MinimumHeight = MinimumSize.Height;
	Control.PreferredWidthRequested += (o, args) => {
		args.MinimumWidth = MinimumSize.Widgth;
