Just wanted to post a comment regarding getting the original height and width of the element in IE that you don't have in other browsers. After looking for a workaround I stumbled across your page and also stumbled across a different way of doing and that's getting the 'scrollHeight' and 'scrollWidth' value. (which will suffice in most cases)
This way the filter doesn't need to be removed and the original value doesn't need to be saved.
