Mathias Agopian a44b041639 we need to guarantee that h/w comp set() is called when a buffer has been retired ... removed a test that could violate this guarantee. note that we have no proof tha this ever happened, but consequences could be hard lock-ups. the code here was intended to track the region to update for displays that can do partial update. the logic discarded the update entirely if that region was empty. instead we just redraw the whole thing (note that we should never be there with an empty region and retired buffers though).
