	* gtk/gtktreeview.[hc]: Patch Thomas Broyer from
	<tbroyer@ltgt.net>. Expander arrows are now attached to a specific
	column and follow it when draged, rather than a location in the
	view. "expander_column" property and drawing functions changed
	accordingly.  Fixes bug #55942.

	(gtk_tree_view_{set,get}_expander_column): Now works with a
	GtkTreeViewColumn* instead of int.
