Well this is one of the most basic things you'd expected from a tweening 
engine, I really thing it should be prioritized.

It is not that basic, considering we're talking about speed-based tweens and 
not regular ones, and I actually removed that option because I thought it would 
create confusion (and couldn't find a good use for it). But I was probably too 
strict, so I implemented it and voilà. Please test it out and let me know if 
you encounter any issue :)

There are a lot of places where it could be useful. Examples would be:

The firing animation of a missile, speed-based, where its slower at first and 
faster later on.

Smoothed look-at, again speed-based since you don't need to make it happen in 
an instant when the difference is great.

That's why I thought it's basic. The only way I found to do it was manually 
computing time from the difference between Vector3s and Quaternions (iTween did 
it automatically, which also made porting tweens a bit more hassle). But maybe 
I missed something? Anyhow I'm really glad you took the time for implementing 
it (and so blazingly fast too). Thanks a ton!
