Use cal_client_get_objects_in_range (print_day_details_cb): Callback used

2000-08-15  JP Rosevear  <jpr@helixcode.com>

	* gui/print.c (print_month_small): Use
	cal_client_get_objects_in_range
	(print_day_details_cb): Callback used to create columns and fill
	events into a day view.  Code should be shared with e-day-view
	in reality.  Maybe need to go back to layout.[hc] a bit later
	(print_day_details): Use cal_client_generate_instances with
	above callback. Iterate over results to expand events to fit.
	(print_day_summary_cb): Callback to build list of event info
	for a day
	(print_day_summary): Use cal_client_generate_instances with
	above callback to generate the required event info for printing
	(print_todo_details_cb): Callback used create list of todo info
	(print_todo_details): Use cal_client_generate_instances with
	above callback to generate required todo info for printing.

	* gui/layout.[hc]: No longer used.
