bug#8608: 24.0.50; unable to set alpha frame parameter from emacs

[Jan Djärv]

Hello.

The code that sets alpha in Emacs was wrong, it made assumptions about window 
order that isn't true for Compiz.  It was a bug for other window managers as 
well, as they shall copy such properties from the Emacs top level window to 
any parent it may have put on the Emacs top level window.

Fix checked in for the trunk.
