Assigning negative height or width in animation causes IE to throw an error

[stickmus]

If you try to assign a negative height or width for an animation IE throws an error, which then breaks future animations for that dom element. See test page here:

Is it ever okay to set negative height/width? This sounds like a programming error. jQuery doesn't try to validate all the inputs it's given, that would take quite a bit of code.

This was actually just fixed recently, to take care of easing animations that went to negative numbers. It will be in 1.4.
