-The timeline modes can be any combination of 'antialias' (average color),
-'slitscan' (center pixel), 'keyframes' (one or more frames per cut), 'audio'
-(waveform), 'cuts' (antialias with cut detection overlay, for debugging) and
-'data' (each frame resized to 8x8 px).

-One or two timeline heights can be specified, larger height first. The timeline
-widths will be 1 px per frame for the first one, and 1 px per second for the
-second (smaller) one. If the wide option is set, large 'keyframeswide' tiles
