Do we have anything like the getCameraOrientation() function that was added to the 1.3 camera in https://github.com/mozilla-b2g/gaia/pull/15188/files ?

It seems like we might need that to get selfie pictures with the right orientation on Tarako, but that is just a guess. 
It feels a little like a different bug, but keep int in mind, please because that issue might come back at us.
