Handle more (hopefully all) edge-cases when updating `opacity_target_old`: * `MAPPING` transitions to `FADING` if new target is reached. Otherwise no update. * `FADING` clamps to current `opacity` if old target is too small. * `UNMAPPING`/`DESTROYING` clamps to current `opacity` if old target is too small.
