wtf is react-rTween ?

react-rtween is an additive tweener for react

It allow :

• Additive tween ( applying forward and backward multiples tween on same properties )
• Scrollable & swipeable animations
• SSR rendering of =! scroll / swipe position
• Hot switching scrollable anims ( responsive )
• Predictive inertia
• etc...

Todo :

• Nice examples
• Better scroll support
• Full css support ( full background transitions )
• Doc, tests & clean
• SVG bindings
