Implementing a custom transition

Hi,

The way I understand it you can create a custom 'easing' transition to change the animation between nodes. What I would like to do is instead of scrolling, have a cross-fade occur. I don't see of a way to specify the animation from one of the theme overrides? Looking in the jCarousel source, it looks like it's hard-coded to not include the easing parameter. So is there some way I'm missing to implement this?

Thanks - this module is saving me a huge amount of time :)
