You have two ways to test if this is a true svg graphic or a raster
graphic:

- open the file with an SVG editor or viewer, zoom the picture: if this
  svg has only a raster embedded, then when zooming you get to see the
  image individual pixels as squares
- open the file with a plain text editor: in a real svg graphic you see
  only mark up code; if a raster image is embedded, you see the image
  content, encoded. This is the case with the image of the link from
  above: 

<image x="1100" y="7000" width="25401" height="8461" xlink:href="data:image/png;base64,

and you see all the image content encoded.  So it is a raster image
embedded on an svg file, not a real svg graphic.  You can zoom the real
vector graphics without quality loss, you don't get "pixel squares"; of
course, wikipedia explains it better than me ;)
http://en.wikipedia.org/wiki/Raster_graphics

With the original SVG graphic it's possible to generate raster graphics
of any size without quality loss.
