/**
 * GUI: virtual card component for popup hint (move mouse over card to show a hint)
 * <p>
 * Use case: you don't have a real card but want to show a popup card hint.
 * <p>
 * Howto use:
 * - call "init" on new card;
 * - call "onMouseEntered" to prepare;
 * - call "onMouseMoved" to draw;
 * - call "onMouseExited" to hide;
 * <p>
 * Hints:
 * - for game GUI: you must init with gameId (otherwise you can't see it)
 * - for non-game GUI: no needs in gameId or bigCard (bigCard is a panel with card image)
 * - if you want to show card immediately then use init + onMouseEntered + onMouseMoved
