Measured with gpu/probe exp43-47, bit exact: - New vertices are interpolated from the inside vertex, t = d_in / (d_in - d_out) with d = z + w through the GE adder, using the GE's reciprocal; out - in is truncated to float24 before the multiply by t, and t and each coordinate use float24 products and adds. - With one vertex outside, the quad is split from the vertex before it in the GE's order: (p, a, b) and (p, b, n). The GE takes odd strip triangles in reverse and fan triangles in order, so SendTriangle now says when the vertices it gets are reversed from that.
