If SVG was offered as a "rendering" option, this would not be an issue.

there is no such image format. once you commit something to a given number of pixels, there is no going back. in the same way, you cannot get a higher resolution from your sceen by using a microscope. the only way to get what you want would be to re-render the data on demand, i.e. by using VMD or a raytracing program.
the next best thing is to render the image at a much higher resolution, i.e. with more pixels (i.e. like using a higher resolution screen in my example above).
that requires that you use a rendering program, e.g. Tachyon, to generate the image and change the flags that define the resolution of the resulting image.
