Creates a gtk.CellAreaContext to be used with area for
all purposes. gtk.CellAreaContext 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 gtk.CellAreaContext
which was used to request the size of those rows of data).
