Added e-cell-date.c, e-cell-date.h, e-cell-size.c, and e-cell-size.h.

2001-01-15  Christopher James Lahey  <clahey@ximian.com>

	* Makefile.am: Added e-cell-date.c, e-cell-date.h, e-cell-size.c,
	and e-cell-size.h.

	* e-cell-date.c, e-cell-date.h: New cell to implement displaying a
	date.

	* e-cell-size.c, e-cell-size.h: New cell to implement displaying a
	file size.

	* e-cell-text.c, e-cell-text.h: Got rid of the filter arguments.
	Replaced them with the ability to subclass ECellText and override
	the get_text method.  Added free_text to override if your get_text
	implementation returns allocated memory.

	* e-table-extras.c (ete_init): Added "size" and "date" cells to
	the default ETableExtras.

+ * @justify: Justification of the string in the cell.
+ *
+ * Creates a new ECell renderer that can be used to render dates that
+ * that come from the model.  The value returned from the model is
+ * interpreted as being a time_t.
+ *
+ * The ECellDate 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, bold, color and a date filter.
+ *
+ * The arguments "strikeout_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 date should be rendered with strikeout, 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 dates.
