	* libnautilus-private/nautilus-icon-container.c (get_cmp_point_x),
	(compare_with_start_row), (compare_with_start_column),
	(next_row_rightmost), (next_column_bottommost),
	(same_column_below_highest), (keyboard_home), (keyboard_end),
	(record_arrow_key_start), (keyboard_arrow_key), (keyboard_right),
	(keyboard_left), (keyboard_down), (keyboard_up),
	(button_press_event):
	Split out fallback function that determine the rightmost icon on the
	bottom row, which used to be inside same_column_below_highest().
	Add a similar concept for the vertical layout.

	Vertical layout: Move to the last item when pressing the right arrow
			 key in the penultimate column, below the last item.
				next_row_rightmost().

	Horizontal layout: Move to the last item when pressing the down arrow
			   key in the penultimate row, right to the last item.
				next_column_bottommost().

	Remove arrow_key_start, and use arrow_key_axis_x/_y, for
	horizontal/vertical position constraints in
	compare_with_start_column() and compare_with_start_row().

	Fixes #549686, at least for LTR.

	* libnautilus-private/nautilus-icon-private.h:
	Remove unused arrow_key_axis and arrow_key_start variables.
