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.
