Uh... Seems so.
I'm guessing that those lines are an interference pattern created from
bitmap transform. Also, it seems that if you squeeze the circle to,
say, half of it's height, the result is quite good. If you squeeze the
circle to one tenth of initial height, all you see is those lines.
To fix this, I think the scaling factor should be calculated in some
other way in nr-filter.cpp and transformer should use bilinear or

Odd, wonder why I'm not seeing those messages.
It seems though, that those are not caused by a real problem, but by an
off by one error in debugging routine:
pixblock-transform.cpp:36 should have
