If you only plan to have simple (text-only) tooltips on full items, you
can use this function to have #GtkIconView handle these automatically
for you. @column should be set to the column in @icon_view’s model
containing the tooltip texts, or -1 to disable this feature.
When enabled, #GtkWidget:has-tooltip will be set to %TRUE and
@icon_view will connect a #GtkWidget::query-tooltip signal handler.
Note that the signal handler sets the text with gtk_tooltip_set_markup(),
so &, <, etc have to be escaped in the text.
