public virtual void get_preferred_height (CellAreaContext context, Widget widget, out int minimum_height, out int natural_height)
Retrieves a cell area’s initial minimum and natural height.
this will store some geometrical information in context along the way; when requesting
sizes over an arbitrary number of rows, it’s not important to check the minimum_height and natural_height of
this call but rather to consult get_preferred_height after a
series of requests.
