Gaia Ajax: AspectHoverable
AspectHoverable can dispatch server events on true MouseOver/MouseOut events for a control.
It automatically takes care of the bubbling problem and only dispatches the event if you have subscribed to it and if
it actually is a true MouseOver of that Element.
Also notice that the MouseOver and MouseOut events for many of the Gaia Ajax controls actually use AspectHoverable under the
hood by using AspectBindings. In many cases it's more appropriate to use those events directly instead of adding the Aspect.
