why the textureunit did not support the 'modulate_x2' mode?

the blend parameter in ogretextureunit only support 'replace, add, modulte alphablend', how about get more blend mode?
i found the lightmap in the tutorials did not have a diffuse texture, but i could not get a way to obtain a good result while the diffuse texture added.

think thats an extended blendmode, I asked about that too, since I like using modulatex2 for lightmaps and bloom eithout shaders. He said he may get extended blendmodes into the next build.

Looking forward to those too, Since I keep having to edit my materials in notepad at the moment
