I'm just doing a handheld panorama taken from the top of a reservoir
dam. The banister gave me grief as there were visible blending
artifacts. So I remembered having read of the new algorithm here and
got the latest code from the repo and built it, resulting in enblend
4.1-101796703d73.

When stitching my pano, first thing I noticed was that it was really
slow. When I looked at the output, there was a gaping black hole,
where enblend had simply forgotten one image. I couldn't quite believe
it and reran the stitch to the same effect. When I switched back to
the old algorithm using --primary-seam-generator=nearest-feature-
transform, it was still slow but at least it included all images. Am I
missing something - like, does the new algorithm need the images in a
particular sequence? Does anyone else have this problem?

In the parts where the new algorithm did place seams (so, between the
images it used rather than ignored, it's a 6+1+2), the seam placement
was a great deal better than that of the old algorithm. This makes me
want to have the new one working very much, never mind it's slow! If
needed, I can try and reduce the problem to a simple test case,
compress the images and file a bug report.
