Zoom cards on long press

[Tomin1]

It could be nice if player could zoom in cards with a long press. Currently it is a bit difficult to find cards in a stack. In GNOME Aisleriot player can right click cards to raise them on top of others to see them better and that works well with a mouse, but it wouldn't work on touch screen where fingers usually cover touched cards. Instead we could make the card grow upwards or to its left making the symbols on top left of the card to move next to the finger. Dragging enlarged cards should probably be allowed. This needs some experimentation to see if it is actually a feasible solution.
