     *
     * With fixed function vertex processing, Direct3D knows 2 different fog input sources.
     * It can use the Z value of the vertex, or the alpha component of the specular color.
     * This depends on the fog vertex, fog table and the vertex declaration. If the Z value
     * is used, fogstart, fogend and the equation type are used, otherwise linear fog with
     * start = 255, end = 0 is used. Obviously the msdn is not very clear on that.
     *
     * FOGTABLEMODE != NONE:
     *  The Z value is used, with the equation specified, no matter what vertex type.
     *
     * FOGTABLEMODE == NONE, FOGVERTEXMODE != NONE, untransformed:
     *  Per vertex fog is calculated using the specified fog equation and the parameters
     *
     * FOGTABLEMODE == NONE, FOGVERTEXMODE != NONE, transformed, OR
     * FOGTABLEMODE == NONE, FOGVERTEXMODE == NONE, untransformed:
     *  Linear fog with start = 255.0, end = 0.0, input comes from the specular color
     *
     *
     * Rules for vertex fog with shaders:
     *
     * When mixing fixed function functionality with the programmable pipeline, D3D expects
     * the fog computation to happen during transformation while openGL expects it to happen
     * during rasterization. Also, prior to pixel shader 3.0 D3D handles fog blending after
     * the pixel shader while openGL always expects the pixel shader to handle the blending.
     * To solve this problem, WineD3D does:
     * 1) implement a linear fog equation and fog blending at the end of every pre 3.0 pixel
     * shader,
     * and 2) disables the fog computation (in either the fixed function or programmable
     * rasterizer) if using a vertex program.
     *
     * D3D shaders can provide an explicit fog coordinate. This fog coordinate is used with
     * D3DRS_FOGTABLEMODE==D3DFOG_NONE. The FOGVERTEXMODE is ignored, d3d always uses linear
     * fog with start=1.0 and end=0.0 in this case. This is similar to fog coordinates in
     * the specular color, a vertex shader counts as pretransformed geometry in this case.
     * There are some GL differences between specular fog coords and vertex shaders though.
     *
     * With table fog the vertex shader fog coordinate is ignored.
     *
     * If a fogtablemode and a fogvertexmode are specified, table fog is applied (with or
     * without shaders).

            the left to the right end of the viewport (with all matrices set to
            be identity), the x coords of both ends of the line would be not
            -1 and 1 respectively but (-1-1/viewport_widh) and (1-1/viewport_width)

            1.0 / Width is used because the coord range goes from -1.0 to 1.0, then we
            divide by the Width/Height, so we need the half range(1.0) to translate by
            half a pixel.

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