listen for the time editors to change

2002-08-14  JP Rosevear  <jpr@ximian.com>

	* gui/dialogs/cal-prefs-dialog.c (init_widgets): listen for the
	time editors to change
	(cal_prefs_dialog_start_of_day_changed): make sure the start is
	never after the end
	(cal_prefs_dialog_end_of_day_changed): make sure the end is never
	after the start

	* gui/e-meeting-time-sel.c
	(e_meeting_time_selector_set_working_hours): make sure to show a
	minimum of 1 hour for work day

	* gui/e-day-view-main-item.c (e_day_view_main_item_draw):
	calculate the work/not working color boxes to the nearest pixel,
	rather the the nearest time division

	Fixes #10286, #26285
