--- Comment #14 from Esme Povirk madewokherd@gmail.com --- If I hack it to draw a solid line instead, it still hangs.
If I hack GdipDrawPath to use the software path, it does not hang. I don't know why that would be, since it also works by creating a region for the line and filling the region.
It still doesn't draw anything, so it's possible we're skipping the draw entirely.
