add insert_child_anchor signal, bug #50245

2001-02-19  Havoc Pennington  <hp@redhat.com>

	* gtk/gtktextbuffer.h (struct _GtkTextBufferClass): add
	insert_child_anchor signal, bug #50245

	* gtk/gtktextbtree.c (_gtk_text_btree_insert_child_anchor): change
	from create_child_anchor, so the anchor is passed in

	* gtk/gtktextchild.c (gtk_text_child_anchor_new): new function
	(_gtk_widget_segment_new): have the child anchor object passed in,
	instead of creating it.

	* gtk/gtktextbuffer.c (gtk_text_buffer_modified): rename
	to gtk_text_buffer_get_modified
