Code review comment for lp:~smspillaz/compiz-core/compiz-core.work_923683

I think I may have confused the situation by suggesting the regression introduced by this branch is bug 928173. The symptoms are actually slightly different. It's only a theory that it's the same bug, because the size of the horizontal offset looks similar.

The bug I see with this branch would be worthy of a new bug report (a critical regression) that I don't want to log. And we won't have to log that bug so long as it's fixed before this branch is merged.
