Tracing images to grease pencil objects creates sometimes artifacts, as seen, for example, when tracing the attached image. {F9910821}
I have found the same behavior both in the 2.92 release and in the current 2.93 master.
The artifacts are caused by a variable that's not initialized or updated when finding a point tagged as POTRACE_CORNER.
This patch solves this issue.

This patch is the result of the GSoC 2020 "Editing Grease Pencil Strokes
Using Curves" project. It adds a submode to greasepencil edit mode that
allows for the transformation of greasepencil strokes using bezier
curves. More information about the project can be found
here: https://wiki.blender.org/wiki/User:Filedescriptor/GSoC_2020.
This patch adds a new operator to convert a black and white image into
grease pencil strokes.
If the image is not B/W, an internal conversion is done.
This is the first operator using Potrace, but we expect to add more features in next Blender versions.
