audio/video to carry subtitles, song lyrics (with or without karaoke data),
etc., but doesn't have to be.

Series of curves (splines, segments, etc.) may be attached to various
properties (text position, font size, etc.) to create animated overlays.
This allows scrolling or fading text to be defined. This can even be used
to draw arbitrary shapes, so hand drawing can also be represented by a
Kate stream.")
