Get widgets working on the btree/buffer side. Display of them still

Browse Source 
2000-11-03  Havoc Pennington  <hp@redhat.com>

        Get widgets working on the btree/buffer side. Display of them
	still doesn't work.

	* gtk/gtktextview.c: start implementing child widget stuff

	* gtk/gtktextiter.c (gtk_text_iter_get_child_anchor): new function

	* gtk/gtktextlayout.c: handle embedded widgets

	* gtk/gtktextdisplay.c: handle embedded widgets

	* gtk/gtktextchild.c: Implement all the child anchor goo

	* gtk/gtktextbuffer.c (gtk_text_buffer_create_child_anchor): New
	function

	* gtk/gtktextbtree.c: Add child anchor table to the btree struct
	(insert_pixbuf_or_widget_segment): abstract out common portions of
	creating a child anchor or a pixbuf segment.
	(gtk_text_btree_create_child_anchor): new function
	(gtk_text_btree_unregister_child_anchor): new function

	* gtk/gtkmarshal.list: added VOID:OBJECT,INT,INT for the
	allocate_child signal on GtkTextLayout

	* gtk/gtktextiter.c (gtk_text_iter_get_pixbuf): fix bogus return
	values
	(gtk_text_iter_get_child_anchor): new function

	* gtk/gtktextbuffer.c (gtk_text_buffer_real_changed): Add a
	default handler for the changed signal, which calls
	gtk_text_buffer_set_modified(), instead of just always emitting
	changed then calling set_modified() manually. I guess this is
	maybe more flexible. It seems logical.
