Creates a #GtkCellAreaContext to be used with @area for
all purposes. #GtkCellAreaContext stores geometry information
for rows for which it was operated on, it is important to use
the same context for the same row of data at all times (i.e.
one should render and handle events with the same #GtkCellAreaContext
which was used to request the size of those rows of data).
Return: a newly created #GtkCellAreaContext which can be used with @area.
