-For Teleport, Chakart and Hamilton at least: a piece should be attached to mouse cursor,
-waiting for a click dropping it somewhere. In BaseGame: find the appropriate place to call eg. Board::setHoverPiece(),
-which should be in effect when hovering over position only (#gamePosition), and cancelled when receiving the
-message stopHover() for example.
+On smartphone for Teleport, Chakart, Weiqi and some others: wait re-click to confirm "touch" move (in Board.vue)
