 387          * too, which would allow fog coord emulation in a fixed function vertex pipeline replacement.
 388          *
 389          * Fog vs texture: We apply the fog in the vertex color. An app could set up texturing settings which
 390          * ignore the vertex color, thus effectively disabling our fog. However, in D3D this type of fog is
 391          * a per-vertex fog too, so the apps shouldn't do that.
 392          *
 393          * Fog vs lighting: The app could in theory use D3DFOG_NONE table and D3DFOG_NONE vertex fog with
 394          * untransformed vertices. That enables lighting and fog coords at the same time, and the lighting
 395          * calculations could affect the already blended in fog color. There's nothing we can do against that,
 396          * but most apps using fog color do their own lighting too and often even use RHW vertices. So live
 397          * with it.
