+- orientation: The orientation of a device (typically an image sensor or a flash
+ LED) describing its mounting position relative to the usage orientation of the
+ system where the device is installed on.
+ Possible values are:
+ 0 - Front. The device is mounted on the front facing side of the system.
+ For mobile devices such as smartphones, tablets and laptops the front side is
+ the user facing side.
+ 1 - Back. The device is mounted on the back side of the system, which is
+ defined as the opposite side of the front facing one.
