I don't see why this prevents us from integrating this functionality 
into GTK+.
Since a clipping bitmap is always set for drag icons, the onliest bad 
thing that can happen is that your drag icons aren't semi-transparent at 
locations where the alpha value is between 1 and 254, right?
Since Metacity and many other WMs support this as of writing, you can 
always tell people to grab a recent WM.
