 *   2 After rasterization, also print the triangle count and other
 *     information that may be interesting.
 *   3 Also print the number of seconds it took to render the entire scene,
 *     according to wall time.
 *   4 Also print the number of triangles as they are being rastered.  This
 *     uses ANSI escape codes which may not be supported on all terminals.
 *     It also causes a lot to be printed, so it can actually decrease render
 *     performance, especially on a slow (or remote) terminal.
 * The default setting for this option is 3.
