A new module to provide RasterSetup and advanced triangle/line/point
functionality layered on top of the software rasterizer. An example entrypoint: void _swsetup_Triangle( GLcontext, GLuint, GLuint, GLuint, GLuint ) will coerce the software rasterizer to draw flat, twoside-lit, unfilled and offset triangles (including decomposition to points or lines).
