Look into refactoring scroll effects to use Animations and Tweens in the event details page

[roughike]

The code for calculating the scrolling effects is currently really ugly and hard to maintain.

I have a feeling that these could be easily done with anAnimationController and Tweens. The AnimationController would be used manually; the value property can be manually updated when the current scroll offset changes.
