parentNode is null or undefined in draggable resizeable custom overlay with image. GMaps v3
I have made a resizeable custom overlay with an image and it works, you can see it here,  
[debug](http://wifigator.com/dash/debug2.php).  In the upper right hand corner and lower left corner there are some red corner icons that you can drag and resize the image and overlay.   The problem is that when you make the image smaller, it leaves behind remnants of the lager scale images.

I then added a function to remove the overlay before drawing the new one, straight out of the example, overlay.onRemove();  It worked, but as soon as you un click the marker it gives the error "parentnode:  object is null or undefined", you can see it here [debug2](http://wifigator.com/dash/debug.php)

If you view the source on them, the drag listener in on line 173 and calls the overlay = new USGSOverlay(bounds, srcImage, map, 'yes'); on line 194.

The function is on line 71. and looks for ifDrag and then deletes the previous overlay, I am baffled as to why it works but as soon as you un click the marker it throws the error and breaks the script.

It would be awesome if someone could provide me with a fix or workaround to the error. This is a very nice feature to have and am too close to give up. Thanks.
