To add viewBox in SVG

[hellomaya]

To have fabricjs used in real production, the best way I think we will need SVG to be the final output, and when fabricjs export the canvas content to SVG, it usually used px as the unit, and because the size difference between the screen and the print, we will have to resize the canvas to be much more bigger to achieve better image quality, SVG do have a feature called viewBox, if we can use viewBox when we export the canvas content to SVG, we will be able to redefine the coordination system of SVG, that means, we don't have to resize canvas, we only change SVG, so we can achieve the size what we want to, so do you think that could be another new feature in current version of fabricjs? http://tutorials.jenkov.com/svg/svg-viewport-view-box.html#coordinate-system-units

When I am checking the source of fabricjs, and going to fix that I found it support viewBox attribute, I am sorry for my roughness, and I will close this issue.
