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.
