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

[Xavier Pennec]

Hi Stacho & Jonny

Yes, I had this behaviour a few month ago on windows 10, but I did not 
found yet the time to characterize the problem with a minimal example to 
ask for help.
I will try to see if I can reproduce it with a small example as soon as 
I find time. I remember that this was also happening with previous 
versions of therion (I tested at least 5 of them), I wonder if this not 
coming from the graphics library that displays the scraps.
