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).
