This property creates an extensible mechanism allowing special visual effects to be applied to content. There are currently three categories of filters – Visual filters and Reveal/Blend Transition filters. Multiple filters can be applied to a selector to produce interesting results, with the order of application often playing an important role in the final visual result. Current filters only apply in a visual context, but the extensibility of the property could allow for other capabilities.
