  * reducing test.jpg with GIMP reveals a bug in EXIF parsing (not yet fixed)
  * MakerNote parsing:
    + add support for Panasonic cameras
    + for the following manufacturers we do not check the camera model, this
      gets all cameras, even yet unreleased ones to work:
      + Canon
      + Panasonic
      + Casio
      + Olympus
      + Fujifilm
