Part of Klondike Solitaire.

 1"""Title menu shown before the first deal.
 2
 3A full-rect ``Control`` that dims the table behind it and offers the two
 4entry points: a fresh deal, or resuming the save on disk (offered only when
 5a save file exists). Everything is anchored, so the card stays centred at
 6any window size.
