Sequencer, scaling and audio synch
Don't scale proxies, same as we do in gooseberry, also for sound synch
give a small window around sound where frame is just pushed forward.
Avoids video jumping in the cases when video renders faster than sound
(yes, weirdly enough it happens sometimes). There might be a few jumps
but results looks smoother here.
