2000-10-02  Havoc Pennington  <hp@pobox.com>

        * gtk/gtktextview.c: text_window_* weren't static and should have
	        been.
		        Start work on child widgets; not yet complete,
syncing to
        office computer.

	        * gtk/gtktextchild.h: change this to contain a public interface,
		starting work on child interfaces.
		        * gtk/gtktextchildprivate.h: move private interfaces here

			* gtk/Makefile.am: update to reflect gtktextchildprivate.h

			* gtk/gtktextview.h, gtk/gtktextview.c, gtk/gtktextbuffer.h,
			gtk/gtktextbuffer.c, gtk/gtktextiter.h, gtk/gtk/textiter.c,
			gtk/gtktextmark.c: copyright notices

			* gtk/gtktextmarkprivate.h: reformat, and put _ in
front of
        internal functions

	* gtk/gtktextchild.c (_pixbuf_segment_new): put _ in front of
	internal function

	* gtk/gtktextlayout.c (gtk_text_layout_get_line_display):
	Reformatting
