	Editable cell window placement and RTL fixes.

	* gtk/gtktreeview.c (gtk_tree_view_button_press),
	(gtk_tree_view_bin_expose), (gtk_tree_view_get_cell_area),
	(gtk_tree_view_create_row_drag_icon): Only add indentation to x
	if !rtl,
	(gtk_tree_view_create_row_drag_icon): Iterate over columns in reverse
	direction if in rtl mode.

	* gtk/gtktreeviewcolumn.c (gtk_tree_view_column_cell_process_action):
	horizontal_separator is not part of the real background area width,
	add 2 * focus_line_width to real_cell_area.x and not
	real_background_area.x, fix up event coordinates check in the
	PACK_END loop, also set depth to zero at the end of the PACK_END
	loop,
	(_gtk_tree_view_get_neighbor_sizes): also add column_spacing for each
	visible cell.
