*
* 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.

* 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

* Vertex shaders work in a simmilar way, but need more testing
