* This translates to: *
***********************
Set the blender to first multiply fog colour with Z-Value placed on Vertex-Alpha, Add the result of the ColourCombiner and then divide the whole thing by Z-Value + 1.
On the second Pass, Multiply the result of the ColourCombiner (CLR_IN) with ColourCombiner_Alpha (A_IN) and add fist pass Multiplied by 1-A

So if we add arbitary numbers we can see whats happening.
Lets call the FOG 255, Z 0.5, CC 128, CC_A 1.
[-----------MUX1--------] [--------MUX2--------]
We end up with ((255*0.5) + (128*1))/1.5 = 170.333 ((128*1)+170.333)/1.5 = 198.89
This of cource is done for Red Green and Blue on every pixle displayed on screen.
The Colour Combiner Applies Tri-Linear Filtering and then applies the shading of the object.
In logical Terms the Colour Combiner should come first

This is a generic render mode.
It will produce a Fogging Tri-linear Filtered Mip-Maped textured shaded triangle.
It will also be z-buffered and Anti-Ailised.
If the texture contains Alpha or is a greyscale type (4/0 3/1 4/4 8/8) then it will be transparent HOWEVER, since the Zmode is Opaque it will either not draw objects behind this OR it will not Anti-Ailise edges,

This is a 1 Cycle un-textured tri.
It will NOT FOG.
It will ALWAYS appear Grey.
Its Preset Name for Blender is AA_ZB_SUB_SURF which means Subsurfaces.
"Sub surface mode, SUB_SURF, is intended to be used as a way to get an opaque object upon which an antialiased transparent surface can be overlaid. The coverage values from the transparent surface will fill in the zapped coverage values from the initial opaque surface. "

This means that the Trees can FOG, they are Anti-Ailised and are transparent. They do Not Z-Buffer correctly, While they Compare their Z Value to other objects, they do not update their value. This is why they can overdraw themselves in some locations. Luckelly their Z-Value is usually higher than all the objects in Surface
The Blender is forced. This may be the key to detail maps?
The Combiner for the trees will do Tri-linear Filtering and then use the shade given to them via Vertexes.
The Alpha however is special, it Multiplies the first Tree image on Mip-Map Level1 (n+1) with the detail map on Level 0 (n).
on The second pass it combines this with FOG (since on Fogged tri's, FOG replaces Shade Alpha)
GE uses a different Rendermode from PD but the same Combiner.
Grids Rendermode is
(CFOG, AIN, CIN, 1)|(CIN, AIN, CMEM, 1-A); //This part is the same
Z_OPA; CVG_CLAMP; A_CVG; IM_RD; Z_UPD; Z_CMP; AA_EN
// Opaque Surface, Coverage is clamped, Uses Alpha for Coverage, they ZBuff corectly.
I also notice the C0 command is different which is bound to change the BA command.

Ok, lets deal with a whole DList as something is missing.
