[0.3.3] Started producing SVG without width, height and viewBox

See original GitHub issue

Hi @btel ,

due to my rendering regression tests in xiangqi-setup I noticed that things broke when trying to upgrade to svgutils 0.3.3. What happens is that the width, height, and viewBox parameters are no longer included in the written SVG file. Here’s what that looks like in Inkscape: The dotted line is where the viewbox was with svgutils 0.3.2, the solid frame is where the new defacto viewbox is:

svgutils_0_3_3_viewbox

Here’s a diff of before and after, with regard to the SVG output.

I have a feeling that #58 is causing this: .width and .height (with no underscores) are no longer set? Is that a bug or a feature? How can I make svgutils 0.3.3 put width, height and viewBox into SVG output again?

Thanks and best, Sebastian
