#known bugs:
- viewbox/width/height do not correctly apply if documents only contain an object (not a path). After converting it to path it works. Seems to be a bbox problem
- note from 07.05.2021: seems if the following order is viewBox/width/height, or width/height/viewBox, the units are not respected. So me mess around a little bit
#Todo
- add some way to handle translations properly
