Comment 25 for bug 91786

Last time I looked into this it required a bit of a hack where you draw the shadows in two stages. The first stage is drawing the panel shadows only then running through the windows a second time drawing shadows for everything else. Upstream was very resistant to such a change happening there and I actually think the next release of compiz (when/if if ever happens) would make such a change impossible to do in this way. Not really sure what to do here to be honest.
