# A card doesn't record to which stack it belongs; only the stack
# records this (it turns out that we always know this from the
# context, and this saves a ``double update'' with potential for
# inconsistencies).
#
# Public methods:
#
# moveTo(x, y) -- move the card to an absolute position
# moveBy(dx, dy) -- move the card by a relative offset
# tkraise() -- raise the card to the top of its stack
# showFace(), showBack() -- turn the card face up or down & raise it
#
# Public read-only instance variables:
#
# suit, rank, color -- the card's suit, rank and color
# face_up -- true when the card is shown face up, else false
#
# Semi-public read-only instance variables:
#
# item -- the CanvasItem representing the card
# x, y -- the position of the card's top left corner
#
