403 * ignore the vertex color, thus effectively disabing our fog. However, in D3D this type of fog is
404 * a per-vertex fog too, so the apps shouldn't do that.
405 *
406 * Fog vs lighting: The app could in theory use D3DFOG_NONE table and D3DFOG_NONE vertex fog with
407 * untransformed vertices. That enables lighting and fog coords at the same time, and the lighting
408 * calculations could affect the already blended in fog color. There's nothing we can do against that,
