Loading jquery.vegas.js in footer?

Just wondering why you load jquery.vegas.js in the footer. Looking at the vegas page they show loading that javascript file then executing the code afterwards. Or maybe it doesn’t matter? I’m using your plugin on every page of my site and trying to eliminate or at least minimize the white flashes that occur going from page to page. Doesn’t happen every time and it’s worse on IE8 and Chrome than in Firefox.
