 954      * Rules for vertex fog with shaders:
 955      *
 956      * When mixing fixed function functionality with the programmable pipeline, D3D expects
 957      * the fog computation to happen during transformation while openGL expects it to happen
 958      * during rasterization. Also, prior to pixel shader 3.0 D3D handles fog blending after
 959      * the pixel shader while openGL always expects the pixel shader to handle the blending.
 960      * To solve this problem, WineD3D does:
 961      * 1) implement a linear fog equation and fog blending at the end of every pre 3.0 pixel
 962      * shader,
 963      * and 2) disables the fog computation (in either the fixed function or programmable
 964      * rasterizer) if using a vertex program.
 965      *
 966      *
 967      * If a fogtablemode and a fogvertexmode are specified, table fog is applied (with or
 968      * without shaders).

3898             As a consequence if you want to correctly draw one line exactly from
3899             the left to the right end of the viewport (with all matrices set to
3900             be identity), the x coords of both ends of the line would be not
3901             -1 and 1 respectively but (-1-1/viewport_widh) and (1-1/viewport_width)
3902             instead.
3903
3904             1.0 / Width is used because the coord range goes from -1.0 to 1.0, then we
3905             divide by the Width/Height, so we need the half range(1.0) to translate by

3908             The other fun is that d3d's output z range after the transformation is [0;1],
3909             but opengl's is [-1;1]. Since the z buffer is in range [0;1] for both, gl
3910             scales [-1;1] to [0;1]. This would mean that we end up in [0.5;1] and loose a lot
3911             of Z buffer precision and the clear values do not match in the z test. Thus scale
3912             [0;1] to [-1;1], so when gl undoes that we utilize the full z range
