Hello.

I just tested the new demosaicing algorithms for Fujifilm EXR cameras (X10) which are mentioned in the press release (nowhere in the readme, though). While overall there are improvements that make the RAW match the ooc JPG much more closely in fine resolution detail there is a considerable issue.

There are demosaicing artifacts happening at 90 degree edges/lines that meet like this: ⅂

What seems to happen is that pixels are diagonally swapped so that part of the edge pixel now is placed outside the edge and an outside pixel is placed inside the edge.
