Colorify the month item and prepare it for prelighting here.

1998-09-30  Federico Mena Quintero  <federico@nuclecu.unam.mx>

	* goto.c (create_days): Colorify the month item and prepare it for
	prelighting here.

	* main.c (color_props):  Changed the default colors to something
	not dull.

	* year-view.c (compute_min_size): New function to compute the
	minimum size of the year view properly.
	(year_view_size_request): Added two new fields to the year view
	structure that contain the minimum size.  Return this in the
	size_request method.
	(year_view_new): Call compute_min_size to save the minimum size
	for later use.
	(idle_handler): Make it resize the items correctly.

	* gnome-month-item.c (gnome_month_item_set_arg): Reshape when
	necessary.  This is needed becaues we now actually calculate a
	minimum size for the month item based on the font sizes and paddings.
	(check_heading_sizes): New function to calculate a minimum size
	based on the headings' dimensions.
	(check_day_sizes): New function to calculate a minimum size based
	on the day number labels' dimensions.
	(check_sizes): New function that computes a minimum size for the
	month item.
	(reshape): Now calls check_sizes() to ensure a minimum size for
	the month item.
