Elements with Dynamic Heights

[jwfurness]

In our system, we have sections that can change height dynamically. I would like to use parallax on some of these sections, but as the heights change, there's overlap in the parallax images. It looks like there is a resize function in parallax.js that adjusts the height of the parallax mirror. Is there any way to manually cause the parallax layers to redraw/update size in my event handler?
