        First, the purpose of this computation is to update a product's
        write_date whenever its template's write_date is updated.  Indeed,
        when a template's image is modified, updating its products'
        write_date will invalidate the browser's cache for the products'
        image, which may be the same as the template's.  This guarantees UI
        consistency.

        Second, the field 'write_date' is automatically updated by the
        framework when the product is modified.  The recomputation of the
        field supplements that behavior to keep the product's write_date
        up-to-date with its template's write_date.

        Third, the framework normally prevents us from updating write_date
        because it is a "magic" field.  However, the assignment inside the
        compute method is not subject to this restriction.  It therefore
        works as intended :-)
