Now the question is how this could be solved. One of their suggestions is use even-integer width, but that from principle wouldn't be true, since it still overlaps by half-a-pixel (so one full and two 1/2 pixels). So the other option is to apply transformation matrix to the whole visualization? So much work for a sharp line. :( And considering that it seems to be blurred in one axis differently than the other... I'll play some more with it. Pete
