The following is a guest post by Amelia Bellamy-Royds. Amelia has lots of experience with SVG, as the co-author of SVG Essentials and author of the upcoming Using SVG with CSS3 and HTML5. Amelia and I both will be speaking on SVG at the upcoming RWD Summit as well! Here, she shares an epic guide to scaling SVG, covering all the ways you might want to do that. It's not nearly as straightforward as scaling raster graphics, but that can be good, because it opens up interesting possibilities.
