	Fix bug #157254.

	* libplanner/mrp-time.c: Add new (temporary) API and use it to
	improve performance a lot with large projects. Long term we should
	either switch to it completely or rename it.

	* src/planner-gantt-background.c: (gantt_background_draw):
	* src/planner-gantt-header.c: (gantt_header_init),
	(gantt_header_expose_event), (gantt_header_motion_notify_event):
	* src/planner-gantt-print.c: (print_time_header):
	* src/planner-scale-utils.c: (planner_scale_format_time):
	* src/planner-scale-utils.h:
	* src/planner-task-dialog.c: (task_dialog_update_schedule_label),
	(task_dialog_calendar_changed_cb): Use the new API.

	* tests/time-test.c: Remove obsolete test.
