jquery, write a function to get both new and old window.width
<p>how do i write a function that detects and caches the start and the end of a window.width resize</p>

<p>the width in the the .resize(funciton{}) changes instantly when resizing, but I'm after the differences between the old and new size every time it resizes.</p>

<p>update---</p>

<p>I Need to catch the diffeence so that I can do a width: '+=diff' to an element </p>
