   4 ## @brief Extract embedded jpegs from a raw file
   5 ##
   6 ## Use exiftool if it detects a higher number of preview
   7 ## images, otherwise use exiv2 if available
   8 ## - exiv2 does not see the largest preview image in a .cr3 file.
   9 ##
  10 ## Note that exiftool is noticeably slower than exiv2
  11 ##
  12 ## - Display a list of the embedded files
  13 ## - Extract the selected image to a tmp folder
  14 ## - Rotate image if exif data is available
  15 ## - If jpgicc is installed, correct for currently selected rendering intent
  16 ## - Store in a new file
  17 ## - Set Geeqie focus to the newly generated image
