use requestAnimationFrame instead of setInterval for animations, when available

Blocked by: Blocking:

requestAnimationFrame is a mechanism meant to tell the browser that you wish to perform an animation; this requests that the browser schedule a repaint of the window for the next animation frame.

Full description here:


  • let the browser choose the best 'animation tick' rate (instead of our arbitrary 13ms)
  • greatly reduce animation CPU usage when switching tab
  • helps keep animation synchronized

Full list of claimed benefits here:

Currently supported in Firefox, chromium and Chrome dev channel.

Adding it to jQuery is a minor change (7 lines of Javascript).

Oops, this is an enhancement, not a bug sorry.

I wish I could fix that by myself.

It’s a very good idea, but probably best implemented in the future when production browser actually support (it instead of only pre-release ones since it could be subject to change) :)

As I said in the pull request, there's absolutely no need to hurry in merging this patch.

I wrote it because I had a good idea of how it good fit into jQuery code and I wanted to do some tests.

Of course, merging it doesn't make sense before Firefox4 and Chrome10 are officially out :-)
