[Therion] Drawing lines with graphic tablet

Thu Jul 14 09:01:16 CEST 2022

Hi Axel,

I don't think handling of scraps was changed at all, but in my testing it
has always achieved better performance than XTherion. The only thing that
it doesn't handle as well are large XVI files, because XTherion renders
those very efficiently. Other than that, big scraps should work just the
same as small scraps.

If you could file a bug report for this that would be very useful.
Thanks,
Csongor
