* 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
