The fuzzer detected a bug in our handling of null child processors. Rather than attempt to further tweak a hand-rolled effect, it seemed more productive to convert it into a full-fledged .fp file. This provides a very high degree of confidence that the basics are done properly, for a relatively low amount of effort. Contrast calculation has also been optimized slightly. The original shader calculated (1+c/1-c) separately for every pixel. This is now done once, in Make(). Also, if contrast adjustment is set to zero, the contrast block is fully omitted.
