 * (T194731) DifferenceEngine properties mOldContent and mNewContent and methods setContent, generateContentDiffBody, generateTextDiffBody and textDiff are deprecated. To interact with a single slot, use a SlotDiffRenderer (and subclass it to customize diff rendering); to diff custom (e.g. unsaved) content, use setRevisions. Subclassing DifferenceEngine should only be done to customize page-level diff properties (such as the navigation header).
