API consistency with jQuery.animate()

[ChrisKam]

Hello,

thank you for making this awesome plugin! I'm currently migrating some Fancybox stuff over to transit.js (as the default animation looks terrible in some browsers) and I have noticed something:

In jQuery, you can pre-define an object which you then pass into .animate like so:

var ani = {
left: "+=50px",
top: "+=100px",
opacity: 1
}

and pass it in like this

$("element").animate(ani, {
duration: 500,
complete: functionname
});

which I think makes the code really nice and clean. With transit.js, I would have to do this

$("element").transition({
left: ani.left,
top: ani.top,
opacity: ani.opacity,
duration: 500,
complete: functionname
});

...which is redundant. $.extend obviously solves this issue but I really like how jQuery's animate() does that implicitly for you. For consistency's sake, I think it would be nice if jquery.transit would behave the same way.
