--- Comment #5 from Paul Gofman gofmanp@gmail.com --- The patch tested here is committed, but this is not a complete fix yet, see Comment #2 and Comment #3. Lines in the image concerned in Comment #3 exhibit the aliasing effect which needs a true "halftone" interpolation to be avoided. I don't know actually if this bug should be closed or not.
