Sequencer display overlay option, this can show a border area from another time to help compare for color grading.

- Okey sets the border in the display.
- Okey resets the frame offset in the sequencer timeline.
- ghost icon in the header can enable/disable.
- frame offset can be relative or absolute (lock icon)

Not very happy that this commit adds a call to BKE_animsys_evaluate_animdata(scene, ...) in do_build_seq_array_recursively()
without this the offset frames dont have fcurves applied.
Though we will need something like this for prefetch frames to work too.
