• does not make any changes to the svg area but rather clones it and then modifies it.

• fixes reported styling issues
• now uses the board name as filename

fixes #15

Hit me up if something else is missing or not working.

One more thing: Would you be interested in PNG Export as well (in another PR)?
I would need to add a package for that https://github.com/canvg/canvg

Actually just using all stylesheets in document.stylesheets doesn't work for some users. One users had a browser extension that adds stylesheets and trying to access them resulted in a cross origin policy exception. What I've come to do is to match on the href of the stylesheet and include matches of boad.css or boards/tools/*.css.

I've added your remarks and put in the stylesheet filtering mentioned by @sents

Also added support for IE download, but I think that was the last time I handled something extra for IE^ (Just so you know: https://death-to-ie11.com/)

Some other tools also don't support IE:

Ah yes, that was my selector pull request. I'm working to make it IE compatible.

@DanielHabenicht if I will merge this PR then this image download tool will create the problem ( download will works but if you will open that downloaded image then it will create the problem) , same thing is happening with this PR as well do you know how to solve this?

[DanielHabenicht]

Can you describe the problem? (In your Issue and CC me)
I think the main problem ist the image embedding, not working seperatly (meaning only with SVG spec).
