SVG background-image support

[ericorruption]

I'm using an svg as a background-image, but cssgrace throws the following error:

'TypeError: invalid svg at Object.calculate (/Users/username/code/project-name/node_modules/image-size/lib/types/svg.js:61:13)

Is this because the plugin doesn't support .SVG files? I'm using an image generated by Illustrator. If the plugin doesn't support SVG it should skip svg files, I think.
