    # The mk1's origin was the bottom left corner of the bottom pinky key.
    # But it later got rotated by the bottom *right* corner as the pinky angle
    # and then rotated again for the inter-half angle so [0, 0] was nowhere on
    # the actual result.
    #
    # Since the new origin is the center of the pinky home, we have to convert
    # the old, round 250 width to this new coordinate system if we want backward
    # compatibility. The following snippet was used to arrive at this distance.
    #
    # old_origin = new Point(7, 7 + 19)
    # old_origin.rotate(5, [14, 0])
    # old_origin.rotate(-20, [0, 0])
    # new_width = 250 - (2 * old_origin.x)
