     *
     * 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 Direct3D depth bias is specified in normalized depth coordinates. In
 * OpenGL the bias is specified in units of "the smallest value that is
 * guaranteed to produce a resolvable offset for a given implementation". To
 * convert from D3D to GL we need to divide the D3D depth bias by that value.
 * We try to detect the value from GL with test draws. On most drivers (r300g,
 * 600g, Nvidia, i965 on Mesa) the value is 2^23 for fixed point depth buffers,
 * for r200 and i965 on OSX it is 2^24, for r500 on OSX it is 2^22. For floating
 * point buffers it is 2^22, 2^23 or 2^24 depending on the GPU. The value does
 * not depend on the depth buffer precision on any driver.
 *
 * Two games that are picky regarding depth bias are Mass Effect 2 (flickering
 * decals) and F.E.A.R and F.E.A.R. 2 (semi-transparent guns).
 *
 * Note that SLOPESCALEDEPTHBIAS is a scaling factor for the depth slope, and
 * doesn't need to be scaled to account for GL vs D3D differences. */
