Enblend and difficult seams

[Yuval Levy]

When dealing with six pictures to blend meeting around the same spot, I
encountered an issue (see the four rainbow-colored images in the
"Hickups And Fixes" section of [0].

I pinged Christoph and he pinpointed the issue to be likely in the
seam-line vectorization or de-vectorization code. He has added a
debugging switch to the Enblend code [1]

I can't believe it! I wish I could pin-point more precisely the code
where the bug lies. To my understanding: somewhere before line 880 in
mask.h?

I think there is more brain to be picked on Hugin-PTX than in a private
conversation with half a dozen developers.

For users: a possible temporary workaround is on my blog.
