''' '''
# The source code is a horrible mess. I apologize for your inconvenience, but hope that it still helps. Feel free to improve :-) '''
# Keep everything python2 compatible as long as people out there are using Inkscape <= 0.92.4! KNOWN BUGS:
WONTFIX: clipping of paths doesnt work
WONTFIX: if there is any object with opacity != 100%, inkscape exports some objects as bitmaps. They will disappear in CutStudio! The same problem also occurs if the alpha value of stroke or fill color is not 100%.
WONTFIX: filters (e.g. blur) are not supported
