Support pause/resume on transform

[jongmoon]

Description

Now the pause/resume is not working on transform. But for more various animation effect, transform support is needed.

Steps to check or reproduce

$el.animate({"transform": "rotate(20deg)"}, 4000);

//before 4000 ms, you can pause or resume
$el.pause();
