Removing shadows underneath windows when using xcompmgr

[Joel Feiner]

I hate to say it, but it is the only usable compositing manager for me. 
   Compiz is close, but still is laggy in places (scrolling especially), 
not to mention unstable and hard to configure.  Don't even get me 
started on KDE 4's KWin, because half the time, its compositing doesn't 
even work, to say nothing of performance (and really, there's not much 
to say about its performance: it just isn't there).  If you have another 
suggestion, I am open to hear it.
