Pinboard mods

I'm looking at adding support for individual icon layouts per desktop to 
ROX-Filer.

I have a klunky setup at the moment  where I can switch with a ROX-Filer -
p=$DESKTOPNAME,  It is not terribly speedy and also flickers.

Most of flicker should be fixable with a clean-slate function in place of 
Destroying and creating a new window.  I can make a clean slate function 
that gets called instead of create_pinboard_window() which can decide 
whether to reuse the existing window.

I'd like to catch _NET_CURRENT_DESKTOP within ROX-Filer,  but I'm not 
certain how to detect root window messages in gtk.  So far all of the 
code I have found from other people detecting desktop changes have either 
been using libwnck or polling.  

Any advice on how to do this would be appreciated.  I've spent an age 
trying to figure out the _NET_CURRENT_DESKTOP  thing.
