Use Pango to draw. (e_calendar_item_class_init): Add font_desc and

2003-02-02  Hans Petter Jansson  <hpj@ximian.com>

	* e-calendar-item.[ch]: Use Pango to draw.
	(e_calendar_item_class_init): Add font_desc and week_number_font_desc
	args.
	(e_calendar_item_get_arg): Ditto.
	(e_calendar_item_set_arg): Ditto.
	(e_calendar_item_draw_month): Use Pango.
	(e_calendar_item_draw_day_numbers): Ditto.

	* e-calendar.c: Use Pango to draw. Specify just the size of the small
	font to use, instead of all aspects of it.
	(e_calendar_init): Produce the small font description and pass it to
	the ECalendarItem.
