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