        * gtk/gtktreeviewcolumn.c
        (gtk_tree_view_column_cell_process_action): constrain cell area to
        passed in cell_area, #147867

        * gtk/gtkcellrenderertext.c (gtk_cell_renderer_text_get_size): if
        ellipsizing, get_size is only 3 chars wide.

        * docs/tree-column-sizing.png: Add Matthias's excellent image.
