A simple color animation utility using the existing animation utility.

Nice and thanks!

I made a simple demo just to see it in action (requires browser that supports input[type=color]) — http://jsfiddle.net/vZrg9/26/

I would wanna make a better demo to put on fabricjs.com (maybe bunch of rectangles stacked together like mosaic and when you hover them, they change into random color, producing sort of a colorful trail when you mouse over entire field of them)

Thanks for the merge.

A nice demo for the color animation would be cool. Just didn't have time yet to work on something, so the commit was just the animation.

Hi, finally got time to make a better example for the color animation that is based on your idea:

Feel free to add it to fabricjs.com

@ChrisBuergi awesome, thanks!
@asturur @Kienz would you guys be able to put it on fabricjs.com when you get a chance? If not, I'll get to it myself sometime soon.
