Listed below are the parameters controlling the flick's playback

• fadeIn: how long to fade from nothing to full colour (constant)
• fadeInOnce: only fade in at the start of the reel if checked, otherwise fade in each time
• pauseStart: display the same start doodle for this many frames
• pauseStartOnce: similarly to fadeInOnce (above)
• pauseEnd: frames to pause at the end of the reel
• pauseEndCycles: how many times do we play the entire reel before we pause the last doodle of the reel
• fadeOut: etc
• fadeOutCycles: how many times do we play the entire reel before we fade out the last doodle of the reel

We calculate these values by dividing the selected time by the frame rate

• fadeInTicks: used to count down the number of frames displayed as we fade in
• pauseStartTicks: ticks counting (as above) the frames where we pause before advancing
• pauseEndTicks: (as above) displaying the last frame
• fadeOutTicks: fading out
• cycles: keep count of how many times we get the the end of the reel
