Canvas

The canvas is the main display area for the frame. No control elements are included in this area. The main display item is a two-dimensional display of the cube. Apart from being simpler and faster to create, such a display makes the representation of cubes of large size practical, and in so doing meets one of the major requirements of the program. In addition the following items appear on the canvas.
