  29 /* Public interface to the swrast_setup module.  This module provides
  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().
