Add a support SVG files

[jurakin]

It would be a good idea to support SVG files so that you don't have to manually draw the path. SVG files are vector images, so the path can be extracted and used to create the drawing.

Hello I agree that it would be a good idea since it is native in SVG but unfortunately I don't have time anymore to implement this. So if you want to make a pull request with this I would be happy to accept it.
