IMHO, we should really not encourage anything based on frame count: nine
time out of ten¹, people use frame counts because they believe it is more
accurate than the same information expressed in timestamp with a simple
multiplication and do not realize that variable frame rate is in fact very
common. Allowing frame counts will cause more fragile scripts on the loose.
