  Hi!

  Ok. Then try this: in line 3958

  change

  dev->bdiff = dev->rdiff + (...);
  dev->gdiff = dev->rdiff + (...);

  to

  dev->bdiff = dev->rdiff;
  dev->gdiff = dev->rdiff;

  and set both values to one. This should result in no line distance
  correction. To fix the resolution is another topic. If you don't mind,
  we'll first try to get the colors working :)
