Changing a filter will trigger this event. It is also triggered when a transition has just been completed. Filters are a MSIE-specific means of providing more attractive on-screen effects when things change.

Calling a function that changes a filter and executes a transition results in a further trigger for this event handler. Thus, you can set up an animation loop with this handler, but be careful to avoid stacking recursions or the browser will crash.
