Code review comment for lp://qastaging/~townsend/compiz/fix-minimize-unredirect-window

Hey Chris, no problem.

I've only had a chance to have a passing look so far, but I'm doing a full test + look now. I still feel like putting the check for w->minimized () after we've built the unredirected windows list feels a little weird, but perhaps my previous approach was too overzealous. I'm just going to try something else now and see how that goes.
