xscreensaver-4.11-1 depends on xloadimage. According to /usr/share/doc/xscreensaver-4.11/README, xloadimage is no longer needed (as of 4.09) - so the dependency can be removed?
Nope, it's still used by vidwhacker and webcollage, among others.
Hm, this actually requires more investigation; they're referenced in the code, but they may not be required in the normal paths.
vidwhacker no long uses xloadimage and webcollage will only use it as a last resort fallback if available (also webcollage is no long built by default). the xloadimage requirement should be removed from rawhide soon.
