 940      * is used, fogstart, fogend and the equation type are used, otherwise linear fog with
 941      * start = 255, end = 0 is used. Obviously the msdn is not very clear on that.
 942      *
 943      * FOGTABLEMODE != NONE:
 944      *  The Z value is used, with the equation specified, no matter what vertex type.
 945      *
 946      * FOGTABLEMODE == NONE, FOGVERTEXMODE != NONE, untransformed:
 947      *  Per vertex fog is calculated using the specified fog equation and the parameters
 948      *
 949      * FOGTABLEMODE == NONE, FOGVERTEXMODE != NONE, transformed, OR
 950      * FOGTABLEMODE == NONE, FOGVERTEXMODE == NONE, untransformed:
 951      *  Linear fog with start = 255.0, end = 0.0, input comes from the specular color
 952      *
 953      *
 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).

1899     the form (a1 <operation> a2). However, some of the more complex operations
1900     take 3 parameters. Instead of the (sensible) addition of a3, Microsoft added
1901     in a third parameter called a0. Therefore these are operations of the form
1902     a0 <operation> a1 <operation> a2, i.e., the new parameter goes to the front.

1905     functions below, expect their syntax to differ slightly to those listed in the
1906     manuals, i.e., replace arg1 with arg3, arg2 with arg1 and arg3 with arg2

3014              * The fixup is required for Prince of Persia 3D(prison bars), while Moto racer 2 requires D3DTOP_MODULATE to work
3015              * on color keyed surfaces. Aliens vs Predator 1 uses color keyed textures and alpha component of diffuse color to
3016              * draw things like translucent text and perform other blending effects.
3017              *
3018              * Aliens vs Predator 1 relies on diffuse alpha having an effect, so it cannot be ignored. To provide the
3019              * behavior expected by the game, while emulating the colorkey, diffuse alpha must be modulated with texture alpha.
3020              * OTOH, Moto racer 2 at some points sets alphaop/alphaarg to SELECTARG/CURRENT, yet puts garbage in diffuse alpha
3021              * (zeroes). This works on native, because the game disables alpha test and alpha blending. Alpha test is overwritten by
3022              * wine's for purposes of color-keying though, so this will lead to missing geometry if texture alpha is modulated
3023              * (pixels fail alpha test). To get around this, ALPHABLENDENABLE state is checked: if the app enables alpha blending,
3024              * it can be expected to provide meaningful values in diffuse alpha, so it should be modulated with texture alpha;
3025              * otherwise, selecting diffuse alpha is ignored in favour of texture alpha.
3026
3027              * What to do with multitexturing? So far no app has been found that uses color keying with multitexturing

3830             As a consequence if you want to correctly draw one line exactly from
3831             the left to the right end of the viewport (with all matrices set to
3832             be identity), the x coords of both ends of the line would be not
3833             -1 and 1 respectively but (-1-1/viewport_widh) and (1-1/viewport_width)
3834             instead.
3835
3836             1.0 / Width is used because the coord range goes from -1.0 to 1.0, then we
3837             divide by the Width/Height, so we need the half range(1.0) to translate by
3838             half a pixel.
3839
3840             The other fun is that d3d's output z range after the transformation is [0;1],
3841             but opengl's is [-1;1]. Since the z buffer is in range [0;1] for both, gl
3842             scales [-1;1] to [0;1]. This would mean that we end up in [0.5;1] and loose a lot
3843             of Z buffer precision and the clear values do not match in the z test. Thus scale
3844             [0;1] to [-1;1], so when gl undoes that we utilize the full z range
