Added 'background_area' calculation to GtkCellAreaClass->foreach_alloc vfunc
This allows us to reduce code allocation code paths in subclasses, as
a result GtkCellArea implements the ->render() vfunc and the subclass
only decides the cell area and background area distributions in a single
code path.
