With tweenlite, can I change the destination values of an existing tween?

TweenMax has an updateTo() method for that, yes, but since TweenLite is intended to be a very streamlined "lightweight" core, it doesn't have that method. Frankly, it's not generally advisable to update values like that - usually if you're trying to update values after creation, there's probably an architectural problem in your code (not always of course). 


And beware that you can't updateTo() plugin-based values. It's a very tricky conundrum because you have to factor in all the possible scenarios, like what if the tween is part-way done and then you update the destination values - should the interpolation be from the original starting value or should it be adjusted to avoid any jumps? If there's an adjustment, what happens when you reverese() that tween - the starting values would shift. Should the duration be reset? What if the tween has already finished - should things just jump to the new values immediately? 


So usually it's better to just create a new tween instead.
