So your proposal is to render each window into a texture, have the card 
generate a set of mipmaps for it, then display that texture on a 
rectangle with a displayed size <= the original texture.

That would cause a noticeable slow-down even with a decent graphics 
system.  I do not think the benefit (such as it is) outweighs the cost, 
so I'm not going to bother trying it.

I didn't think Exposé updated the windows while they were shrunk.  I got 
the impression that they would show a snapshot of the window at the time 
of shrinkage.  Of course, I could be wrong.
