Fetches the #GtkCellArea this @context was created by.
This is generally unneeded by layouting widgets; however,
it is important for the context implementation itself to
fetch information about the area it is being used for.
For instance at #GtkCellAreaContextClass.allocate() time
it’s important to know details about any cell spacing
that the #GtkCellArea is configured with in order to
compute a proper allocation.
