deferred class EV_MODEL General cluster: interface description: "Every figure has a center. The position of the center are the values x and y. It is the position on the screen. The center of the figure can be moved arround and the figure can be rotated around its center and scaled in x and y direction. 2*pi is a full rotation. The direction of a rotation is clockwise."
