Relayout() private méthode

Redo layout. Should produce the same segments as FullLayout, but assume that segments for text up to details.StartChange may be reused (if not affected by changing line breaks), and segments after details.StartChange+details.DeleteCount may be re-used if a line break works out (and after adjusting their begin offset).
