Hey Greensock
Would be great to have the progress() function return 0-1 normalized with the selected easing.
I just animated the rotation of car wheels, and needed that rotation to match the easing of the tween of the car's movement.
Ended up using my own method, by fetching one of the tweened properties ( (current_value-start_value)/(end_value-start_value) ), but a generic progressWithEasing(), or another property to the progress() method, like 'normalize with easing' or something would be great...
Cheers.
