Comment 10 for bug 1020410

Fixed, but some of the symlinks aren't standard (gtk-2.0 and gtk-3.0 are linking various files to each other; should only be one way). I'll fix that now.

This was fixed by adding an image entry to the "murrine-scale" style with the image as the hovered slider SVG. Also, I removed the "orientation" stuff from the style so that it's simpler, but it still works well AFAIK.
