Causes the minimum and/or natural width to grow if the new proposed sizes exceed the current minimum and natural width.
This is used by gtk.cell_area_context.CellAreaContext implementations during the request process over a series of gtk.tree_model.TreeModel rows to progressively push the requested width over a series of gtk.cell_area.CellArea.getPreferredWidth requests.
