set an image's Realtime Texture Mapping to Reflection via Python?

The UV/Image Editor panel has an option that gives the current image reflection mapping so that it is reflective when viewed in the 3D panel’s Textured view. Is there any way to enable this reflective mapping via Python? I’ve looked through the documentation but can’t find anything. It’s not essential, but it’d be a nice touch for a script I’m making.

I’m interested, did you find your way ?
I suppose it would be easier to do in GLSL mode, using texture channels,

Well, I can already do the reflective effect in the Game Engine by mapping the texture channel to Refl. I suppose that’s the best I can do for now, since my laptop can’t do GLSL mode.
