Option to use custom deltaTime, allowing pause menus to use iTween

[GoogleCodeExporter]

I think it would be a great option to allow using deltaTime as calculated 
inside the iTween script off of Time.realtimeSinceStartup to allow pause menus 
to use iTween for animations.

Ack, I didn't see an option to change the type. Sorry about that :/

Not sure I understand you on this.  Can you explain some more?

Allow the end user to switch between Unity's Time.deltaTime and one calculated 
in the script. This will prevent changes to Time.timeScale stopping the 
functionality of iTween.

Sorry, I want to make sure I understand this 100%... 

Right now iTween actually does its animation in an Update loop the option to 
switch this to FixedUpdate() as well as have everything correctly work on 
Rigidbodies will be available soon.  

How would you propose I alter things to allow timeScale changes to not affect 
iTween's animations?

Thanks!

Keep track of the last Time.realtimeSinceStartup, and subtract new time from 
old to get the deltaTime that is unmodified by the timeScale changes.

For example (not tested; off the top of my head):
float lastTime;
float customDeltaTime;
void Update()
{
    customDeltaTime = Time.realtimeSinceStartup - lastTime;
    lastTime = Time.realtimeSinceStartup;
    //Do stuff with the delta time
}

And again, allow this to be optional, as slowing time/pausing time could still 
be very useful.

I'll see about perhaps adding this.  Thanks for the idea.

This issue has my vote. I just ran in the same issue that setting 
Time.timeScale to zero will also stop all animations created with iTween. 
Although there are a lot of situations where this is the behaviour you'd 
expect, however there are also situations where you don't want this to happen. 
For example when pausing the game and animating a GUI menu with the option to 
continue playing the game.

Those who want to pause iTween animations should also use iTween.Pause() when 
setting timescale to 0.

I'm open to code additions if someone wants to tackle this.  Thanks!
