Note that SurfaceToolImpl defines two CommandTool commands which call SurfaceViewer.CreateSurfaceViewer and MakeSurfaceTool. These procedures create the two viewers used to interact with AlgebraicSurfaces. ASViewers creates a color surface viewer and ASGrayViewers creates a black-and-white surface viewer.
