- * The triangle_span structure is used by the triangle template code in
- * s_tritemp.h.  It describes how colors, Z, texcoords, etc are to be
- * interpolated across each scanline of triangle.
- * With this structure it's easy to hand-off span rasterization to a
- * subroutine instead of doing it all inline like we used to do.
- * It also cleans up the local variable namespace a great deal.
- *
- * It would be interesting to experiment with multiprocessor rasterization
- * with this structure.  The triangle rasterizer could simply emit a
- * stream of these structures which would be consumed by one or more
- * span-processing threads which could run in parallel.
