        Draw a line around original_widget.

        Use 'title' to set an initial title text with will be centered
        on top of the box.

        Use `title_align` to align the title to the 'left', 'right', or 'center'.
        The default is 'center'.

        You can also override the widgets used for the lines/corners:
            tline: top line
            bline: bottom line
            lline: left line
            rline: right line
            tlcorner: top left corner
            trcorner: top right corner
            blcorner: bottom left corner
            brcorner: bottom right corner

        If empty string is specified for one of the lines/corners, then no
        character will be output there.  This allows for seamless use of
        adjoining LineBoxes.

        :param satt: dictionary containing attributes for smoothed
                     transitions of bars in UTF-8 display mode. The values
                     are in the form:

                       (fg,bg) : attr

                     fg and bg are integers where 0 is the graph background,
                     1 is the first segment, 2 is the second, ...
                     fg > bg in all values.  attr is an attribute with a
                     foreground corresponding to fg and a background
                     corresponding to bg.

        If satt is not None and the bar graph is being displayed in
        a terminal using the UTF-8 encoding then the character cell
        that is shared between the segments specified will be smoothed
        with using the UTF-8 vertical eighth characters.

        eg: set_segment_attributes( ['no', ('unsure',"?"), 'yes'] )
        will use the attribute 'no' for the background (the area from
        the top of the graph to the top of the bar), question marks
        with the attribute 'unsure' will be used for the topmost
        segment of the bar, and the attribute 'yes' will be used for
        the bottom segment of the bar.

        Store bar data, bargraph top and horizontal line positions.

        bardata -- a list of bar values.
        top -- maximum value for segments within bardata
        hlines -- None or a bar value marking horizontal line positions

        bar values are [ segment1, segment2, ... ] lists where top is
        the maximal value corresponding to the top of the bar graph and
        segment1, segment2, ... are the values for the top of each
        segment of this bar.  Simple bar graphs will only have one
        segment in each bar value.

        Eg: if top is 100 and there is a bar value of [ 80, 30 ] then
        the top of this bar will be at 80% of full height of the graph
        and it will have a second segment that starts at 30%.

    Calculate a rendering of the bar graph described by data, bar_widths
    and height.

    bardata -- bar information with same structure as BarGraph.data
    top -- maximal value for bardata segments
    bar_widths -- list of integer column widths for each bar
    maxrow -- rows for display of bargraph

    Returns a structure as follows:
      [ ( y_count, [ ( bar_type, width), ... ] ), ... ]

    The outer tuples represent a set of identical rows. y_count is
    the number of rows in this set, the list contains the data to be
    displayed in the row repeated through the set.

    The inner tuple describes a run of width characters of bar_type.
    bar_type is an integer starting from 0 for the background, 1 for
    the 1st segment, 2 for the 2nd segment etc..

    This function should complete in approximately O(n+m) time, where
    n is the number of bars displayed and m is the number of rows.
