James,

That's correct that the original patch was designed to fade out over 1.5
seconds (though the comment says 5). My original patch had a slight
error in how it handled slowing the frame rate, but I've sent a fixed
version to Mark. My patch (with the fix I sent to Mark) does use a fixed
number of frames, but it also calls usleep if it needs to wait for a
little bit, after rendering the new frame, so that it fades over
approximately 1.5 seconds. As for slower machines, perhaps I need to add
it some code to prevent the fade from laster for too long -- though it
may not be needed now that the algorithm is much faster. I'll try to do
some testing on an older, slower laptop later today.
