Consider using velocity.js instead of custom transition/animation code

[jouni]

Velocity.js should be as performant or better than CSS transitions and animations.

The benefits of using velocity.js

• a high-profile project with regular updates and a lot of testers
• works with IE8 and IE9 as well
• has a more flexible API to expose to the server side
  • probably a bit faster in some situations, as said on the website

The cons of using velocity.js

• requires jQuery (32kb minified+gzipped) + 7kb of additional JS
