Binary package hint: eog
See attached screenshot for an example.
I picked up an icon in /usr/share/icons/gnome/scalable, and picked the desktop icon as an example.
I wanted to verifiy that SVG/vector graphics look perfectly clean when scaled up significantly, to satisfy my curiosity, and discovered with horror that, well, it looked blurry, just like bitmaps do ! :o(
Hopefully it's just a problem with EOG not displaying them correctly, rather than a particular problem with the Gnome SVG icons, or worse, a problem with SVG images in general...
