Sounds reasonable, George. In regards only to CamTwist, it's probably worth observing that the formal image filter protocol isn't mandatory; consumer patches can be at root in compositions used in CamTwist. The primary reason for formatting a composition to resemble an image filter, in CamTwist, is so it can be stacked amongst other image filters and be a contributor to the image filter chain without completely over-riding any filters which are stacked below it.
