# ************************************************************************
# * New implemetation since 2.10
# *
# * We use a single CanvasImage and call CanvasImage.config() to
# * turn the card.
# * This makes turning cards a little bit slower, but dragging cards
# * around is noticeable faster as the total number of images is
# * reduced by half.
# ************************************************************************
# * Kivy Implementation
# * Wir verwenden ein BoxLayout und installieren je nach Status das
# * face oder das back Image.
