30 * an implementation of the driver interface to t_vb_render.c, and uses
31 * the software rasterizer (swrast) to perform actual rasterization.
32 *
33 * The internals of the implementation are private, but can be hooked
34 * into tnl at any time (except between RenderStart/RenderEnd) by
35 * calling _swsetup_Wakeup().
