Thanks Vasily and all your work on this.
I actually had the raw image dumped in fpi_assemble_lines instead and there
is no more distortion. I tried to debug the exact issue but the code kind
of makes my head spin. I think maybe not all images should be processed
through this function, instead only "fast swipe" images that are shorter
than a certain tolerance should be. Just a thought. If I come up with
something, I'll send it over.
