[Therion] trouble with warped sketches drawing in the wrong place

[Jonny Prouty]

Hi Xavier,

Thanks for your reply. You bring up a good point. I ran a quick check, and
if I generate an SVG instead of a PDF, the faulty behavior also shows up. I
also opened the files on Adobe Acrobat on a Windows 10 machine, which also
shows the faulty behavior.
