In themes-backgrounds-gnome 0.4 (and possibly older), there were some files
which did not meet Fedora's licensing guidelines (or licensing could not be 
determined. They are listed here, so that people can answer the "hey, where 
did my background go?" question.

To make it very clear: NOTHING BELOW THIS LINE IS IN 
themes-backgrounds-gnome >= 0.5
