The renderer backend can now distinguish between jobs. Previously if two jobs of the same frame were started (which is legal if the user made a change while frames were still being rendered), an earlier job in some situations could finish AFTER a later job, and the backend would have no way of distinguishing between them. This meant a frame could be erroneously set to an old value rather than the newest. This commit introduces job identification so that old jobs are automatically discarded.
