Bug#390503: small patch in gtk-window-decorator fixed it on my machine

[yoram bar haim <bhyoram@zahav.net.il>]

I have fixed gtk-window-decorator.c to work with RGB24 instead of ARGB32, this 
seems to allow gtk-window-decorator to work (with compiz) on my machine. I 
hope it will be usable for everybody....

Here is the diff
