Yeah, it is. What I meant to do is allow regualr background setters to 
work with xfce (well, xplanet, basically ;) so if you check the option 
xfdesktop will look for changes in the _XROOTPMAP_ID property and change 
the background accordingly.

It's an attempt to ease one of the annoyances that come with the 
fullscreen background window. Feel free to remove it (or think of a 
better solution :-)).
