yep, commented out for the reason to expose (visually) that there is this option/event; but to avoid being invoked if it is not set from outside. See here for example, https://github.com/mootools/mootools-core/blob/master/Source/Request/Request.js#L27, it's done there the same way.

I also thought about the reposition() option and I already guessed it was your convinient method for that purpose; so I'm fine with merging it into that.
