724 As a consequence if you want to correctly draw one line exactly from
725 the left to the right end of the viewport (with all matrices set to
726 be identity), the x coords of both ends of the line would be not
727 -1 and 1 respectively but (-1-1/viewport_widh) and (1-1/viewport_width)
728 instead.
729
730 1.0 / Width is used because the coord range goes from -1.0 to 1.0, then we
731 divide by the Width/Height, so we need the half range(1.0) to translate by
732 half a pixel.
733
734 The other fun is that d3d's output z range after the transformation is [0;1],
735 but opengl's is [-1;1]. Since the z buffer is in range [0;1] for both, gl
736 scales [-1;1] to [0;1]. This would mean that we end up in [0.5;1] and loose a lot
737 of Z buffer precision and the clear values do not match in the z test. Thus scale
738 [0;1] to [-1;1], so when gl undoes that we utilize the full z range
