hmmmm yeah, that's kinda hacky (though less hacky than dumping it in a 
file).  *sigh*  i hate doing things like that.  i'd really rather 
redesign the problematic part of xfdesktop, but nothing brilliant comes 
to mind.  it's really xfce-mcs-manager's fault, and assuming we have a 
new settings manager for 4.4 (/me pokes benny), it wouldn't need to be 
too much of a long-lived hack, so i guess i'll just stop whining and 
implement it (later, stuff to do now).

i'd like to just stick the property on the screen's (real) root window 
(without a screen number suffix), but then i'm not sure if that would 
work properly with xinerama (xinerama may only give one root window to 
all screens, and even if it doesn't, i don't think there's a method to 
get the per-screen root win).  sticking it on the fullscreen virtual 
root win makes sense, but there's no one-step way of getting the XID of 
that window for the settings manager to use.  so it looks like a root 
property, suffixed by the screen number, will have to do.
