Actually, it's not so simple. I assume the apps that could no longer display SVG images were GTK+ apps. If so, they get the ability to render SVG images from the SVG GDK image loader installed by librsvg2 (/usr/local/lib/gtk-2.0/2.10.0/loaders/svg_loader.so). This is a dlopen'd library, and thus is not really a hard dependency. It's more along the lines of, "if you want this functionality, install this port." Neither gtk20 or cairo can depend on librsvg2, though, or we'd have a circular dependency (as librsvg2 needs gtk20 and gtk20 needs cairo).
