Dean mentioned :hover in the companion thread [1] (somehow this thread got split). How does a coordinate transform API (if I using correct terminology) maps when a filter effect is applied with an event like :hover? Are filters transitional? If so, how is any mapping and the timing of a transition (or animation) sequenced? I believe that before anything is developed fully, much testing with animation and transforms must be done. Dean mentioned testing with animation on webkit-dev [2]. I can help with this (testing with animation and transforms) but I still trying to get one filter to work. The code in example 3 of 3.2.1 for CSS Shaders is foreign to me. For me I would expect to use something like this code. filter: url(distort.svg#distort); Also, is a vendor prefix required like -webkit-filter?
