* startElementAnimation -> animateElement
* animate -> animateItem
* frames -> framesPerSecond
* use the curve shape as provided by the animator
* get rid of the use of QTimeLine
* this cuts down on the number of objects and timer events dramatically in the case of multiple simultaneous animations
* all animations now update on the same tick
* simplifies the management code a -lot- though now i need to do a lot more of the math

TODO: implement interval updating based on the curve shape; otherwise, works pretty well =)
