 These classes handle representing the scene, rendering it, and selecting parts of it. The "scene graph" is the geometric shapes, colors and transparency including hierarchy and instancing, also including the concept of selected part, all handled by the Drawing class. A Drawing can have any number of child Drawings, to any depth, in a tree.  Some classes handle the rendering (View, Camera, Lighting, !CrossFade, !MotionBlur) including effects like silhouette edges, shadows, ambient occlusion, depth cuing, cross fades, and also camera modes like mono, shutter glasses stereo, or oculus rift. Also image save including supersampling, the graphics redraw loop, and interactive center of rotation are managed by View. Selecting objects using a mouse click is handled by View and Drawing.
