IFTTTScrollViewPageConstraintAnimation ignores initial constraint constants

[ashavit]

Hi,
Using IFTTTScrollViewPageConstraintAnimation locks the animated UIView to the center of the screen (or left / right according to the position attribute).
If the constraint used to initialise it using '+animationWithSuperview:constraint:pageWidth:attribute:' had a offset constant other then 0 it is reset and ignored.
Thanx,
Amir
