The SpecialEffect action record got some significant changes in nancy7, including a new type of fade, and the removal of the predefined number of frames to fade. Testing with the original is tough, since it runs way too fast on modern PCs, and the new fade type is never actually used properly, so the current implementation is only an approximation. Also, I've discovered that prior to these changes the entire screen got crossfaded, so the screenshotViewport() function is now entirely removed.
