/**
 * e_cell_size_new:
 * @fontname: font to be used to render on the screen
 * @justify: Justification of the string in the cell.
 *
 * Creates a new ECell renderer that can be used to render file sizes
 * that that come from the model.  The value returned from the model
 * is interpreted as being a time_t.
 *
 * The ECellSize object support a large set of properties that can be
 * configured through the Gtk argument system and allows the user to
 * have a finer control of the way the string is displayed.  The
 * arguments supported allow the control of strikeout, underline,
 * bold, color and a size filter.
 *
 * The arguments "strikeout_column", "underline_column", "bold_column"
 * and "color_column" set and return an integer that points to a
 * column in the model that controls these settings.  So controlling
 * the way things are rendered is achieved by having special columns
 * in the model that will be used to flag whether the size should be
 * rendered with strikeout, underline, or bolded.  In the case of the
 * "color_column" argument, the column in the model is expected to
 * have a string that can be parsed by gdk_color_parse().
 *
 * Returns: an ECell object that can be used to render file sizes.  */
