NXP-15437: Picture orientation is not detected properly

[ThibArg]

Adding the -auto-orient parameter to the ImageMagick command line arguments. Cf http://www.imagemagick.org/script/command-line-options.php#auto-orient

The potential problem is the one described in IM doc...

This operator reads and resets the EXIF image profile setting 'Orientation' and then performs the appropriate 90 degree rotation on the image to orient the image, for correct viewing.

This EXIF profile setting is usually set using a gravity sensor in digital camera, however photos taken directly downward or upward may not have an appropriate value. Also images that have been orientation 'corrected' without reseting this setting, may be 'corrected' again resulting in a incorrect result

...so using -auto-orient could, maybe, lead to incorrect orientation on some pictures?

It's better than not having it. A piece of software that rotated an image without updating the EXIF profile is broken, we can't deal with everything.
