It's hard to be sure, but I think this commit is around the start of 
those changes (at least chronologically):

http://git.xfce.org/xfce/xfwm4/commit/?id=f6d5236b887c062117ee504358e54e63a98e3a54

I assume Olivier has done a fair bit of research on this, so maybe he 
can give some pointers about specific implementation.
