    * gtk/gtktextview.c: Rearrange all the
    scroll-while-dragging-or-selecting code to be different, not
    necessarily better. ;-)
    (gtk_text_view_scroll_to_mark): Change this
    function to take within_margin as a fraction instead of a pixel
    value, and to take alignment arguments (indicating where to align
    the mark inside the visible area)
    * gtk/testtextbuffer.c (fill_buffer): fix bad cast of GtkTextTag
    to GtkObject
    * gtk/gtktextiter.c (gtk_text_iter_set_line_offset): change
    behavior so that offsets past the end of the line are not
    allowed, and an offset equal to the line length moves the iterator
    to the next line
    (gtk_text_iter_set_line_index): make parallel change
    (gtk_text_iter_get_bytes_in_line): add this function
    * gtk/gtktextbtree.c (_gtk_text_line_byte_locate): change handling
    of byte indexes off the end of the line; byte index at the end of
    the line now returns FALSE and doesn't fill in the requested
    values, byte index past the end of the line is an error.  Also,
    don't allow -1 offset anymore, since its meaning is unclear.
    This change exposes some bug in visual cursor motion, where we
    end up with a huge invalid byte index; needs fixing. Symptom of
    bug is a crash when you hit up arrow.
    (_gtk_text_line_char_locate): match the change to byte_locate
    * gtk/gtktextiter.c (find_by_log_attrs): Handle iteration backward
    from start of line properly. fixes bug reported by Mikael
    Hermansson where backspace would delete all text before the
