- * \struct SWvertex
- * \brief Data-structure to handle vertices in the software rasterizer.
- * 
- * The software rasterizer now uses this format for vertices.  Thus a
- * 'RasterSetup' stage or other translation is required between the
- * tnl module and the swrast rasterization functions.  This serves to
- * isolate the swrast module from the internals of the tnl module, and
- * improve its usefulness as a fallback mechanism for hardware
- * drivers.
- *
- * wpos = attr[FRAG_ATTRIB_WPOS] and MUST BE THE FIRST values in the
- * vertex because of the tnl clipping code.
-
- * wpos[0] and [1] are the screen-coords of SWvertex.
- * wpos[2] is the z-buffer coord (if 16-bit Z buffer, in range [0,65535]).
- * wpos[3] is 1/w where w is the clip-space W coord.  This is the value
- * that clip{XYZ} were multiplied by to get ndc{XYZ}.
- *
- * Full software drivers:
- *   - Register the rastersetup and triangle functions from
- *     utils/software_helper.
- *   - On statechange, update the rasterization pointers in that module.
- *
- * Rasterization hardware drivers:
- *   - Keep native rastersetup.
- *   - Implement native twoside,offset and unfilled triangle setup.
- *   - Implement a translator from native vertices to swrast vertices.
- *   - On partial fallback (mix of accelerated and unaccelerated
- *   prims), call a pass-through function which translates native
- *   vertices to SWvertices and calls the appropriate swrast function.
- *   - On total fallback (vertex format insufficient for state or all
- *     primitives unaccelerated), hook in swrast_setup instead.
