 *    Renderer Methods
 *
 *    The renderer methods should be implemented according to the type
 *    of renderer being written.
 *
 *    For the purposes of documentation, there are two basic types of
 *    renderers:
 *
 *        Interactive
 *            Interactive Renderer
 *            WireFrame Renderer
 *
 *        Deferred
 *            a ray-tracer
 *            painter's algorithm renderer (cached in a BSP triangle tree)
 *            an artistic renderer (simulates a pencil drawing, etc.)
 *
 *    The main difference is how each renderer handles incoming state and
 *    geometry.
 *
 *    An interactive renderer immediately transforms, culls, and shades
 *    incoming geometry and performs rasterization. For example, in a
 *    single-buffered WireFrame renderer, you will see a new triangle
 *    immediately after Q3Triangle_Draw (if it's visible, of course).
 *
 *    A deferred renderer caches the view state and each geometry,
 *    converting into any internal queue of drawing commands. Rasterization
 *    is not actually performed until all data has been submitted.
 *
 *    For example, a ray-tracer may not rasterize anything until the
 *    end of the rendering loop, or until an EndFrame call is made.
