v0.20.2

Fixed

• TitleCard and EndCard wrap a long title or second line inside the
  card, and the card grows to hold it. A long line used to run past the
  card's edges, which release videos with long notes showed.
• Centered and end-aligned text with a max_width was drawn beside its own
  box when it was narrower than max_width (a single short line, say). It
  now sits inside the box, so placing it and oxframe check see where it
  really is.
